Kernel errors for cyrus
Sorry for the late reply. I tried to reproduce this but did not succeed. I
applied a few patches and made a new build, so you can try this one:
http://koji.fedoraproject.org/koji/taskinfo?taskID=170944 I don't think it will
I'd be glad if you can provide me a gdb backtrace. If you're able to connect to
the server via IMAP/POP3 (ie. the crash occurs only after you do something or
close the connection), use netstat -tpn to find the process you're connected to
and attach gdb using `gdb /usr/lib/cyrus-imapd/imapd pid'. Then try to reproduce
the crash. Don't forget to install the debuginfo package.
Oh, I forgot:
After attaching gdb, type 'c' to resume the running program. And the backtrace
can be obtained using "bt full".

Sorry for too late reply. I was forgot for this bug.
I received the message in my e-mail and remember for this bug report.
We moved our systems to CentOS 5.1 and we can't reproduce this bug again. I
suppose this bug is solved in the lastest release and suggest to close this bug
Best regards, Ali Nebi!
