I have just increased daemons Happens less but still happens.
System hostname mail.itfor.org Operating system CentOS Linux 5 Webmin version 1.410 Time on system Thu Jul 24 10:25:54 2008 System uptime 1 hours, 0 minutes CPU load averages 32.23 (1 min) 20.95 (5 mins) 17.45 (15 mins) Real memory 942 MB total, 429.82 MB used Virtual memory 1.94 GB total, 0 bytes used Local disk space 106.41 GB total, 17.21 GB used This is from my webmin. I suppose it should be enough for the server. I will put it mor RAM, but I suspect there is something wrong with it. It happen suddently. I would understand that daemons wouldnt be enough if I have added more users. But it started acting like I described apparently without reason.

And Im still looking on the logs for something strange. I found this: Jul 23 15:48:30 mail spamdyke[7315]: ERROR: unable to write 26 bytes to file descriptor 1: Broken pipe That's a good start, but you still haven't said what your server load is like. How many users, how using IMAP, how many using POP3, etc. You may also try increasing the courier daemon in /etc/courier/authlib/authdaemonrc (default is 15). Here's the comments from the file: # You may need to increase daemons if as your system load increases. Symptoms # include sporadic authentication failures. If you start getting # authentication failures, increase daemons. However, the default of 5 # SHOULD be sufficient. Bumping up daemon count is only a short-term # solution. The permanent solution is to add more resources: RAM, faster # disks, faster CPUs...
