I’ve been happily synching DTTG on my iPad 2 and DevonThink Pro Office for months. This past weekend when I attempt to sync DTTG with DevonThink Pro, the sync completes partially and then DTTG crashes. I’ve restarted my iPad and DevonThink Pro Office with no resolution.
I’m running DTTG 1.2.4 on an iPad 2 running iOS 5.0.1, and DevonThink Pro 2.3.2 under OS X 10.7.3.
Try temporarily removing everything in your Mobile Sync group(s) and then syncing. This might narrow whether it’s a document issue that iOS is choking on, or something else. Also, did you reboot the desktop and/or your router – unlikely to be an impact, but there’s the off chance of a transient network/Bonjour issue that’s troubling iOS.
The crash occurs not when moving files from OS X to iOS, but when moving files from iOS to OS X. I’ve rebooted all machines. There are roughly 40 documents that DTTG is attempting to sync back to my OS X box.
