Subject SA-3.2.4 overload
Date Mon, 12 May 2008 17:37:30 GMT
Upgrading from 3.1.7 to 3.2.4 resulted in my server becoming seriously
overloaded. Normally I see 3 to 6 slaves running with scan times
averaging 5-10 seconds. After upgrade, 10 slaves (my max setting) were
busy constantly with scan time running 60 to 300 seconds. CPU
utilization pegged at 100%. Typical traffic is about 10,000/day. 

 

I tried the following, but there was no significant improvement:

Disabling RBL checks

Disabling bayes

Disabling RCVD_IN_WHOIS, RCVD_IN_WHOIS_INVALID, URIBL_COMPLETEWHOIS

 

I installed SA-3.1.9 and processing seemed to return to normal, but I
get the following error:

Slave 0 stderr: Use of uninitialized value in pattern match (m//) at
/usr/lib/perl5/site_perl/5.8.0/Mail/SpamAssassin/Message/Node.pm line
125.

 

Running: 

Sendmail-8.13.8

Mimedefang-2.64

Clamav-0.92

Uvscan-4.32.0

SA is called by Mimedefang (not using spamd). Standard rulesets.

 

Hardware:

HP Proliant DL380 single CPU 2.4GHz, 4G RAM
