I recently installed ClamAV on my Centos 4.1 system (AMD Athlon 64 3500 +, 1GB RAM).
I'm using postfix, with fetchmail to retrieve email from remote ISP accounts and processing emai through a spamfilter plugin, which is a shell script that passes inbounds through clamscan and spamassassin before handing it off to a local procmail for processing and delivery.
Pror to installing ClamAV, the system stayed up for months at a time. Since then, I'm seeing a lot of system freezes and crashes, at least once per day. I'm also seeing a fair number of complaints in the boot log about ACPI errors and the like.
I'm on kernel 2.6.9-11.EL. In the messages log, I can see where just prior to the system freeze, there are a sequence of messages regarding the system's inability to reset the USB adapter, of which no devices are attached. Almost immediately after, I see errors with the system gets error messages on read capacity on the hard drives. After this appears to reset itself, I start seeing kernel messages about available memory dropping from 1GB to less than 1MB.
Any suggestions/advice? Thanks, Bill
