Hi Andrew and Wil!
Thanks for the hints! While it doesn't affect my mailserver now since
I've switched to XFS, it may help me and other list members in similar
situations.
Thank you very much!
Best,
Daniel

I have attached cyrus.conf and imapd.conf.
We are running Cyrus 2.2.12 on SuSE 10.0 on filesystem XFS

I had freezes up to 30 seconds with the same config running on
filesystem ext3, but this error was clearly on server side, the ext3
flushing behavior was so bad that it caused incredible iowait and huge
load and full server stalls.
Not that it matters now since you've switched, but you were probably
suffering from an undersized journal, see:

Or using the wrong I/O scheduler in the Linux 2.6 kernel... Make sure
you use "deadline" instead of the "anticipatory" default I/O scheduler
in 2.6.
