I just had a similar problem here today. I saw that users could connect to the imap port, but not imaps. Also lmtpd process where hung (using cpu) and unable to deliver mail. In the syslogs I saw messages like:
master[18444]: can't fork process to run service imaps: Resource temporarily unavailable The fix was to increase the number of available file descriptors. The default on Debian Linux is 1024. Also, the number of processes is limited to 256 by default. I increased it by putting the following two lines near the top of my cyrus init script: ulimit -n 209708 ulimit -u 2048 Andy On Wed, 3 Sep 2003, Ilan Rabinovitch wrote: > Rob, > > Thanks for your continued help with Cyrus. > > Well I am definately having some cyrus issues.
