[squid-users] c-icap crashing on signal 10 and 11

Hi,

I have squid + squidclamav setup, it serves ~1000 users from FreeBSD
server with 2Gb of RAM. C-icap is crashing frequently on signal 10 and
11:

Feb 26 09:37:57 rsbgyucnix04 kernel: pid 1534 (c-icap), uid 959: exited
on signal 10
Feb 26 09:39:33 rsbgyucnix04 kernel: pid 1536 (c-icap), uid 959: exited
on signal 10
...
Feb 26 10:39:22 rsbgyucnix04 kernel: pid 1553 (c-icap), uid 959: exited
on signal 11
Feb 26 10:39:22 rsbgyucnix04 kernel: pid 5099 (c-icap), uid 959: exited
on signal 11

Perhaps squid-users is not the best place to ask about c-icap problem,
but maybe someone will give me a clue where to start looking.

Both c-icap and squidclamav module are at default settings. RAM is ok,
i tested with Memtest86+.

Thank you in advance,
