Postfix/Courier/Mysql/Squirrelmail slow!

I followed the guide at, and after much searching and tweaking, was finally able to get it up and running.

I currently have two accounts set up, and Both accounts are able to receive and send mail to/from each other through squirrelmail.

However, after having set everything up, the server is responding significantly slower than previously. Furthermore, several alarming lines that keep reappearing in /var/mail/mail.log:


amavis[27187]: (27187-14) (!)ClamAV-clamd: Can't connect to UNIX socket /var/run/clamav/clamd.ctl: Connection refused, retrying (2)

amavis[27187]: (27187-14) (!)ClamAV-clamd av-scanner FAILED: run_av error: Too many retries to talk to /var/run/clamav/clamd.ctl (Can't connect to UNIX socket /var/run/clamav/clamd.ctl: Connection refused) at (eval 100) line 375.\n

amavis[27187]: (27187-14) (!!)TROUBLE in check_mail: virus_scan FAILED: AV: ALL VIRUS SCANNERS FAILED

amavis[27187]: (27187-14) (!)PRESERVING EVIDENCE in /var/lib/amavis/tmp/amavis-20120814T220242-27187

Failed to connect to socket /tmp/fam--

Regarding the second line, the file does at least exist:


# ls -alh /var/run/clamav/clamd.ctl
srw-rw-rw- 1 clamav clamav 0 Aug 14 21:56 /var/run/clamav/clamd.ctl

Regarding the last line, I found a post at I changed the primary group of user 'vmail' to 'vmail' with the following command:


usermod -g vmail vmail
And then restarted postfix and courier, with no change in behaviour.

Any help would be appreciated!

I restarted the server, and it doesn't seem as if there are any more problems relating to amavis or clam. However, the server is still quite slow, and these lines appear very frequently in /var/log/mail.log:


imapd: Failed to connect to socket /tmp/fam--
imapd: last message repeated 5 times

Does the server have enough RAM? I think it should have at least 1GB.

abrichr 15th August 2012 17:42

It only has 512MB. I could certainly upgrade it, but that doesn't address the error in the logfile...

Why not? It is possible that services don't work correctly if there's not enough RAM.
