[Roger Gammans]

Hi

Ok, I have little more infomation . Last week the cyrus
faileed with a corrupted duplicate database, and I have seen that a 
few time on this server now I thing about it.

I've recompiled the sources without stripping and got the following 
backtrace when it failer earlier today from all the ctl_cyrusdb
instances:-
USER       PID %CPU %MEM   VSZ  RSS TTY      STAT START   TIME COMMAND

cyrus    31369  0.0  0.1  3788 1052 ?        S    03:42   0:00
/usr/sbin/ctl_cyrusdb -c

Using host libthread_db library "/lib/tls/libthread_db.so.1".

And the following fomr the lmptd:-

I'm wondering if this happens if a checkpoint occurs during
email delivery and the bug is actually somewhere inside libdb3?
