Same thing here with cyrus-imapd-2.3.8 on Solaris 10 SPARC.

Mine was like this:
Aug 23 09:43:46 castor imap[20105]: [ID 136705 local6.error] IOERROR: opening /imap/spool/K/user/xxxxxx/cyrus.header: Too many open files
The problem is intermittent, only happening with certain imapd
processes. I've noticed it when processing large batches of mailboxes
from a perl script. When I rerun the batch, with a different imapd,
the error doesn't appear. It almost never happens in normal IMAP use.
I don't know how to track it down in these circumstances.
