Hello,
We've recently upgrade to cyrus 3.0.6 and we've been experiencing issue
where imapd will get stuck in an Append and take 100% CPU time. The
client doesn't see anything weird. I've tried leaving the processes to
see if they resolve, but they never did. Doing a kill -TERM twice will
kill the process. I did not notice any issues with cyrus 3.0.5, but
we've been trying to get Xapian indexing going, so we moved to 3.0.6.
Does anyone have any information on where I can look to rectify this
issue?
Here's an example of the ps output:
87556 cyrus 1 102 0 163M 24192K CPU7 7 1:56 96.71% imapd: imap: <client
