Dear helpers I have implemented Cyrus IMAP 2.0.16 on Solaris 2.5 with 128 MB ram. There has been no problems with imap but on a few occasions I have had pop3d hang so that I kad to kill it with a -9 signal. Whilst pop3d was hung the server did not answer any pop3 requests natually imap was OK.
I noticed that if I preforked pop3d daemons in cyrus.conf it was more likely to fail taking about 3 hours to hang. If I did not prefork the daemon it took days (about 12) to hang. I changed the lock routine from flock to fcntl and preforking the pop3d daemon took 7 hours before it hung. The server is now running with out preforking the daemon and I am waiting for it to hang. I ask is it a memory leak on Solaris? Also can I limit the number of requests a particular instance of the daemon answers to like httpd in apache. The server is not heavily loaded with about 4000 pop3d requests a day. I had no problems with qpopper but it forked a new process for each request.
