Sync failing. Possible db corruption

[Michael Sofka]

I have confirmed that running sync_client on individual mailboxes works, 
as does running sync on the accumulated log files.  But rolling 
replication is not working.   After sync_client is restarted there is a 
burst of sync activity on the accumulated log, then nothing.  The new 
log file continues to accumulate, sync_client continues to run, but is 
not processing anything so far as I can determine.

 From the previous day's log I see:

I have not seen a repeat of the DBERROR, and have since restarted cyrus 
services.  So I'm not sure a ctl_cyrusdb -r is needed, or even it it 
would fix things.
