DrWeb continously restarted by watchdog /Cannot create pipe for communication with scanning childs

[ppswede]

Hi,
I'm running CentOS with Paralells Plesk bundled Paralellls Premium Antivirus (Dr Web). After the latest yum updates DrWeb continously seems to crash and be restarted by the Parallells watchdog. By default there were no logs for DrWeb, but when I enable logging to a file it gets spammed continously with the following error:

Cannot create pipe for communication with scanning childs (Too many open files)

And the Drweb process runs at 99% CPU for long periods. This totally fills the disk with logs and I've now disabled logging again and Drweb is back to continously being restarted by the watchdog.

What to do?

Cheers

(Too many open files)

Try to increase the limit in the drwebd init script, adding the following line:

ULIMIT="-n 4096"

Hi, did not work - and does not satisfactory explain why this would be needed now (and not before)?

Looking in the syslog it seems the process is killed by the kernel as it's consuming up all memory

Dec 11 13:02:31 u9227255-01 kernel: Out of memory: Kill process 20296 (drwebd.real) score 409 or sacrifice child

Checking TOP I can see that DrWeb is consuming alot of memory while running
