trouble syncing large database

I have been able to sync smaller DTPO 2.8.6 for sometime. Some to Dropbox and one or two between 2 macs on the same network. I have one database that is rather large I have never been able to sync successfully. I have tried Dropbox, external hard drive (sync store) and direct connection. It always gets about 300 files in and cancels. The error messages in the log vary, but by far the most popular one is “Discontinuation of Transactions: Couldn’t retrieve the content for the record; the record may be incomplete or damaged.”

I have no idea what this means.

I have verified and repaired, optimized, and everything else I can think of.

Any thoughts anyone?
