dcc/razor2/pyzor timeouts anyone?

[Steve Freegard]

Hi All,

I've been having problems with one of my e-mail gateways today - the load
average has been spiking at 1.90 with no unusual increase in mail volume and
MailScanner's been showing in 'top' using 99.9% CPU.

After a bit of investigating (strace -p, debug=yes etc. etc.) - I realised
that SpamAssassin was getting timeouts when talking to Razor2/DCC/Pyzor (my
timeout's are set to 10 seconds for each with SpamAssassin timeout set to 60
seconds in MailScanner.conf)

Also while in Debug=yes/SpamAssassin Debug=yes mode I had an occurrence of
'Process did not exit cleanly, returned 0 with signal 11' just after
SpamAssassin ran it's bayes tests (I think it was about to start a
DCC/Razor2 or Pyzor check) and upon grepping /var/log/messages - I found 64
occurrences of the 'signal 11' in the logs since it's last log roll.

I've since disabled the DCC/Pyzor/Razor2 checks while I work out what's
going on - I also haven't had any sig11's in the log since I've done this
and my load average is down to 0.04 (however it is after 5.30pm here so a
lot of my users have gone home, so it won't get much stressing until
tommorow)

Anyone else experience anything similar?? - I haven't made any changes to
this box for ages.

I'm running MailScanner 4.22-4, SA 2.60, DCC 1.1.36, Pyzor 0.4.0,
Razor-Agents-2.22 and MailWatch CVS on RH9 running on a Compaq Proliant
DL360 G1 933Mhz PIII with 512Mb RAM.

Kind regards,
Steve.
