Spamassassin hanging/dieing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi folks.

I had a FC4 system running exim, clamd.exim and spamassassin. A over 
christmas/new year the server started hanging. 

I took the opportunity to move email to a separate server and built a new FC5 
system just for email.  I'm still using exim, clamd.exim and spamassassin, 
having installed everything from rpms, and copied over the exim.conf and 
local.cf from the old server.

It's still dieing on a regular basis. Looking at top, spamd processes seem to 
be hogging the machine, with clamd.exim processes coming a not very close 
second.

Both real and virtual memory look fine, but CPU usage goes to around 99.7%

I've not changed exim.conf in months, and haven't changed local.cf in a while.  
I've included it below.  All other files have not ben touched and as of the 
rpms.

(The auto_whitelist and auto_learn arn't working either, complainin about file 
permissions, but I don't think they're affecting performance - I could be 
wrong)
# These values can be overridden by editing ~/.spamassassin/user_prefs.cf 
# (see spamassassin(1) for details)

# These should be safe assumptions and allow for simple visual sifting
# without risking lost emails.
