[pkg-kolab] Bug#648147: kolab-cyrus-common: cyrmaster randomly hangs with database error

[Soren Stoutner]

Package: kolab-cyrus-common
Version: 2.2.13p1-0.3
Severity: important

Cyrmaster periodically (about twice a month) hangs consuming all CPU.  When it does, the following error is logged repeatedly in /var/log/mail.warn:

Nov  6 14:40:18 mail cyrus/imap[25614]: DBERROR db5: file /var/lib/cyrus/tls_sessions.db has LSN 11/3596036, past end of log at 1/957228

Nov  6 14:40:18 mail cyrus/imap[25614]: TLS server engine: No CA file specified. Client side certs may not work

I'm not sure if the last line is important as I'm not using client side certs.

Restarting cyrmaster by running

# service kolab-cyrus restart

fixes the problem.  There does not appear to be any permanent damage to the database; after restarting cyrmaster all accounts function normally.  However, during the time that cyrmaster is running at 100% CPU usage, no email can be delivered to the system.
