About 6 months ago, I inherited a number of servers and process and do not have the time to really focus on the true ins and out of what was given to me. Given that I'm really hoping someone can point me in the right direction...
About every 3-5 weeks, we get hammered to the point where out gateways are backlogging over 10,000 across 3, sometimes 4 servers. This includes one server in which BIND is running (wanted to determine some time back if the issue was DNS). SA times are high on most e-mails. No local logging is taking place due to the disk IO which we thought might have been the issue. We have had this issue regardless of the version of Amavisd we have run, regardless of the version of SA, ClamAV and Postfix we have used. We have over time changed the max_server to try and address and this simply consumes more CPU. The only items that I see which have been consistent it the general process, DNS and out pipe the net. Now before someone suggest I refer to the docs to address performance issues, I have, on various occasions . . . also Goggle, bought books, etc... If someone could eyeball the config below and let me know if you see any concerns or areas that might need to be reconsidered, I would greatly appreciate it.... 1. Running and various versions of RHEL (4 and 5) 2. Blocking nearly 5000 hosts and class C and B via IPtables 3. Various postfix header, sender, and body restrictions (not problem is not at the PF level from what I can determine) 4. All processes run in a chroot environment 5. Although some of the processes are older, we have had this issue regardless of versions (we will be upgrading in the next few days, Amavisd, PF, SA, and ClamAV). I can send a copy of the amavisd.conf if needed... Once again, any help would be greatly appreciated -bill- ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
