Hi,
I have an openbsd 3.7 box with clamav 0.86.1 (with --disable-pthreads)
and qmail-scanner 1.25
I have a strange problem that i can't handle,
i'm using qmailscanner with clamscan option, and it scans attachments,
sometimes (especially with big files, eg: larger than 2mb) clamscan
processes hang with 100% cpu usage.
After some hours, as the number of hanged processes grow, the server
start getting killed, and fails to respond to requests. uptime goes to,
say 50.
I'm trying to find a solution to this problem and failed...
Any ideas please?
Ps: I can not use clamdscan cause it fails to compile with
--enable-pthreads, so i think it just doesnt compile clamd without
pthread support...
Below is the output of the following commands:
#ps wwax |grep -i clam
#gdb /usr/local/bin/clamscan 11362
