every day i have to restart the cyrus imap daemon.
sometimes more than once a day. still connected clients could receive

result in "* OK server Cyrus IMAP4 v2.1.18 server ready". it seems master
does not spawn imapd any more. after restarting the master daemon
everything is fine.

this is the only error message in /var/log/imapd.log
- SQUAT failed to open index file

that's no error. Just ignore it.

our server runs on FreeBSD 4.10-RELEASE-p18

following packages are installed:
- cyrus-imapd-2.1.18_1
- cyrus-sasl-2.1.21
- cyrus-sasl-saslauthd-2.1.19
- postfix-2.1.4,1


is this a known problem?
are there any solutions for this problem?

The most likely explanation would be a process limit in cyrus.conf. As an example, we have the following:

imap cmd="imapd" listen="imap.uni-koeln.de:imap" prefork=20 maxchild=300

So if there are already 300 imap processes, no further processes will be spawned.

Cheers, Sebastian Hagedorn
