SA gets slow.
Dear List
I am running qmail + SA + Clamav on FC 5, my problem is when ever
concurrent smtp connections cross 30+ SA gets slow and take too much
time to process mails through qmailscaner
qmail-queue.log
===================================================================
Fri, 29 Feb 2008 09:51:50 PKT:8005: +++ starting debugging for process
8005 (ppid=8002) by uid=508
Fri, 29 Feb 2008 10:11:50 PKT:8005: w_c: elapsed time from start
1199.846234 secs
Fri, 29 Feb 2008 10:11:50 PKT:8005: g_e_h: no sender and no recips, from
via SMTP from 202.76.109.59. Dropping.
Fri, 29 Feb 2008 10:11:50 PKT:8005: ------ Process 8005 finished. Total
of 1199.88143 secs
=================================================================
To remove this problem I kill all qmail-smtp processes. I need its
permanent solution.

Make sure you're not hitting swap (30 concurrent instances of SA may
take over 1GB of memory). Swap thrashing will destroy message throughput.

Get a bigger server(s)?

No, seriously, block the bad emails with a greet delay, validrcptto,
rblsmtpd and other tools before you hand off to SA
