Hello all, We've installed clamav / clamav-milter on a sendmail server with HIGH trafic. It worked well most of the time, but on peak hours (more than 400 concurrent connections per server and 150K mail per hour) the clamav-milter thorws these errors on the syslog and slows down the process:
May 7 09:27:41 rs25s8 clamav-milter[6926]: ClamAv: thread_create() failed: 11, try again May 7 09:28:01 rs25s8 clamav-milter[6926]: ClamAv: thread_create() failed: 11, try again May 7 09:29:58 rs25s8 clamav-milter[6926]: ClamAv: thread_create() failed: 11, try again May 7 09:29:59 rs25s8 clamav-milter[6926]: ClamAv: thread_create() failed: 11, try again May 7 09:30:37 rs25s8 clamav-milter[6926]: ClamAv: thread_create() failed: 11, try again The CPU never went over 70% (1 Xeon with HT). The RAM never went over 80% (1 Gb total + 1,5 Gb SWAP) It just can create the thread! This is always when it tries to create the 257th concurrent thread of clamav-milter. When this happens you can see thru 'ps' near 256 threads of clamav-milter (between 250 and 256, never more). I'm guessing it is a limit on the kernel/libraries/implementation. The system is a RedHat 7.3, kernel 2.4.20-19.7smp compiled by RedHat, glibc-2.2.5-43. We also tried on a Fedora Core 1, kernel 2.6.4 (downloaded and compiled), glibc-2.3.2-101.1.
