High System Load With the SPAM Filter on Openexchange Server
Support knowledgebase (rsimai_slox_spamassassin)
Applies to
Openexchange Server: Version 4
Symptom
When the SPAM filter is activated, the system is sometimes used at full capacity without any apparent reason.
The 'spamassassin' consumes almost 100% CPU and new mail messages can no longer be processed or their
delivery is extremely slow. This symptom is visible e.g.with the command 'top'.
Cause
The spamassassin must be restarted everytime a new mail message is examined. This has turn out to be adverse for
some (big) mails that nearly cause the system to collapse.
Solution
Configure the spamassassin in such a way that a daemon permanently runs in the background.
- To do this, edit the file
/etc/imap/procmailrc
and change the line
| /usr/bin/spamassassin -P
to
| /usr/bin/spamc
- Make the service available at every system start with
openexchange:~ # chkconfig spamd 35
- Start the service
openexchange:~ # rcspamd start
These settings will be standard in future versions of SuSE Linux Openexchange Server.
