We have the following problem with SQL Anywhere 12.1 (latest EBF applied).
The client starts synchronization through a stored procedure that calls start synchronization. The stored procedure is called from the application about every 10 minutes.
Sometimes we have the following entry in the log but we're sure that nobody cancels the synchronization (there's nothing built in to cancel it).
1917,5,7/11/2012 6:36:27 AM,DBSC_EVENTTYPE_ERROR_MSG,0,Stopping synchronization at user's request.
I would have loved to attached the logs to the task but according to the system "Uploading Images is allowed to users with 100 point or more". So logs are below.
Check out this warning in the server log...
W. 2012-07-11 06:36:26. <64> (,74)  The consolidated and remote databases disagree on when the last synchronization took place, the progress offsets are 4080110242 in the consolidated database and 4080024780 in the remote database. The remote is being asked to send a new upload that starts at the last known synchronization point
...did the next upload work? The two logs look like they were cut off.
