It appears this is not a problem with bad tracks. I got down to the last ~50 tracks by moving tracks in and out of a test playlist and syncing. When I was to that point, I could no longer get any further tracks to sync. At that point, I switched to USB and found that everything copied perfectly.

I was hoping to use wifi for my primary syncing method, but it appears to be very unreliable. I would love to provide logs and any other help to get it working better, but otherwise I guess I'll assume wifi sync is broken and just use USB.

Wow, splitting this playlist up to find the bad track(s) is a bit time consuming! I copied all tracks from the auto playlist into a manual one. That sync failed. I split it in half and the second half failed. I split the second half and the second half failed. I split that and both halves failed. I split...anyway, I did a lot of splitting. I stopped at 11:30 last night when the battery on the phone died (wasn't plugged in for testing).

It looks like I have it narrowed down to either one or more of ~150 tracks or something else completely that's just triggered by who knows what. I now know it can't be related to low storage since I have around 85% of the tracks synced and I still have 24Gb left on the card. Apparently the settings transcode the tracks WAY down from FLAC, which was expected. I'm planning on trying again this weekend to hopefully narrow it down to a list of tracks that cause issues. If there is a list, I guess the next question is why. But even then, at least I'll have the ability to wifi sync (hopefully).

Interesting that the sync process was getting stuck for you. The thing I find strange is that I can sync successfully if I pick an album or certain playlists for example but then I can't select other playlists.

As an example, yesterday I tried syncing the one playlist that has never worked with wifi sync and it failed (of course). I then used MMA to select a different set of items to sync (an auto playlist containing the first song on each album) and it worked correctly. I then added to that an artist with ~10 albums and around 100 songs with full success. I turned on the original playlist and it failed. For all of this series, I had the phone located in one spot with good signal (3-4 bars) and plugged in to power with wifi set up not to disable on sleep.

As far as wifi signal goes, I noticed that with only the one router having wifi enabled, I get poor coverage upstairs. When I try to sync in a poor coverage location and it fails, there is a second dialog that tells me that wifi is not enabled and that it needs to be on in order to work. I have to believe that this is conclusive proof that wifi connectivity isn't the primary issue here (though it could potentially be a smaller component exacerbating things).

I have 2 more thoughts to this.
1) If there was a bad track in the playlist (missing/corrupt/some database error/etc), perhaps it is crashing when it reaches that point. I am going to build a few playlists and try various combinations to see if one contains a bad track.
2) I don't know how much space the converted files will take up. I have a 32GB microSD card that I'm using and the playlist size is 30GB. However, I am set up to convert these FLAC files to MP3 prior to transfer. Is it possible that MMW/MMA are calculating too large a transfer and failing ungracefully?

For me it seems to always fail on first attempt, second attempt works fine (other than missing files on Playlist).

My wifi sync generally works, but on a few occasions where it did fail before it got to Analyzing..., I found I had to go into Android's running processes list and force stop MediaMonkey before I could sync again.

That hasn't been a frequent occurence, and I can't honestly remember which build I was on when it last happened. Maybe something to try though if you keep getting failures.

I have 3 wireless routers in the house to provide full coverage. A single router should technically be enough, but I am using one as a switch and the DSL modem also has wifi built in and turned on but isn't used. In any case, I turned wireless off on one of the 2 routers that is used.

So, my configuration is a single router with wifi enabled that I'm connecting to and a second on a different, non-interfering channel that is not used. I then restarted the PC and started MMW without admin privileges (default). I moved the phone to within 5 ft of the wifi router and could see full 4 bands on the wifi fan on the phone. I opened MMA and went to options -> wifi sync -> select sync server -> selected the server -> External SD card -> verified options -> sync now

This has been successful in the past, but it failed again this time. I can say with 99% confidence that WiFi should not be the issue. The only thing I can think of is that the settings inside the sync menu are causing the failure. In this case, I had a single playlist selected containing over 1000 tracks and I had the last 2 check boxes checked (delete tracks on the device). There are no tracks on the phone right now. The phone is basically a clean slate.

MMA v1.0.4.0121
MMW v1630

Upon further inspection, I realized that the 'x' is actually the down arrow. And I know that MMA is connecting to MMW just fine as it is keeping me up to date on last played times. I also found that when I go to settings in MMA and adjust which playlists I want to sync, it updates the settings in MMW correctly. I installed Tiny WiFi Analyzer and it shows that my signal strength should not be the issue.

When it fails, it usually doesn't get to the screen where it shows "External SD Card" across the top. It usually says "waiting for other processes to end", then "connecting to server", then "waiting" or something like that. Sometimes it switches to the screen where it would start showing analysis status before dying. If it starts analyzing, it almost always finishes.

I assume that since it hasn't done the analysis progress bar yet, it can't be a corrupt file or something. If I knew what it was doing during that time or could view the log file, I could probably narrow this down myself.

I tried again this morning just to verify that everything was still ok, and the sync failed. I'm starting to wonder if this is a result of wifi kicking off momentarily. The icon stays blue with 2-4 bars, but I've noticed an up arrow and what looks like an 'x' under it right when the "sync failed" message pops up. I've done a search, but cannot seem to locate a guide for what the different icons mean. I know that having the wifi fan present with 4 bars means I am connected with a strong signal. I know that up arrow indicates that the phone is uploading. But I can't find anything for the 'x'. Unless I'm not seeing it clearly and that's supposed to be a down arrow.

I'm going to try to find a wifi signal monitor/analyzer today to see if that's the issue. I know there are some apps that claim to keep the connection alive, but I would have thought MMA would be doing the same thing when it's trying to setup a sync.

The sync completed successfully this time! Can I assume that the issue was that I wasn't running as admin? I typically just select the icon in the start menu which is not set up to run as admin. I will switch that over now that it appears that that is the issue.

If you are launching from a shortcut, try setting the 'run as administrator' option on the shortcut. Properties/Advanced

I turned off the setting to disable wifi on sleep and set the phone to never sleep. I still got an error when syncing. I then closed MMW and relaunched as an admin and tried syncing again. This time I checked sync all content box as well. That was a bad choice as it started populating all of the albums back from MMA to MMW and now I have a bazillion empty playlists to delete.

I stopped the sync, turned off that option, and synced again. This time it appears to be copying all files that were expected. I haven't verified that as it is in the process of transferring right now. Is it possible that this error only occurs if you do not run MMW as an admin? With Win7, the default is to run as a user and you have to right click "run as admin" to get full rights so I typically don't bother.

I deleted the profile and created a new one. The sync was working fine until I started running low on power. I plugged it into the USB on my laptop (not the MMW server) and that stopped the sync since it wanted to switch to USB. I restarted the sync after plugging the phone into the wall and it failed. I generally have 2-4 bands on my wifi, so I assumed the signal was good strength. I suppose it's possible that a momentary disconnect in wifi could be happening though since I've never checked.

The other thing I thought of was what happens when the phone turns the screen off. I checked my settings and it looks like I was set to turn off wifi when sleeping unless charging. I assumed that if an app was using the wifi, it would keep it active, but now I'm guessing that's not the case. Peke, can you verify what setting you have your phone on? I'm at work so I can't test now but I plan on switching to "always" and trying again.

Is there something I can try on this end? Maybe deleting the profile and recreating it. I've tried that before, but since it's not working anyway I might as well. Anything else?

I'm unable to replicate, Synchronized aprox 1500+ tracks with various setup combination of Clean MMA, Updated MMA, No profiles, No settings. The only time MMA sync failed is when I got out of Range of my Wi-Fi.

Yes, that was a typo. I meant 1630.
