I'll try to run a full reconstruct on the message store. What risks are there running a reconstruct while users are accessing their email?
Thanks for any help,

I was able to get the truss output of one of the imapd processes that died. I also have the core file that was generated. Is there anything I can do with the core file to see what was happening at the time it died? Here's the last few lines of the truss output if it helps.

After the upgrade to Cyrus IMAP 2.2.5 (SASL 2.1.18), I've been seeing a lot of these errors in the logs:

I grepped for the process id's that exited in the log file and see that they are all imapd processes from various users. I've been reconstructing their mailboxes hoping that was the cause, but I was wondering if there is a way to get a better trace of what is happening. It seems hard to get an strace or truss on the imap process since you don't know which one will die. Is there any technique to watching these processes? Is there anything else I should be looking for? Below is the configure commands I used to build imap and sasl. I used gcc 3.3.2 on Solaris SPARC 9.
Thanks in advance for any advice,
