What if run from console

> clamd --debug

And then look log/syslog for ErroR messages ?

[goliy]

Something news:
Feb 19 00:31:12 clamd[11486]: MaxThreads * MaxRecursion is too high: 25500, open file descriptor limit is: 11095
Feb 19 00:29:40 freshclam[8625]: Invalid DNS reply. Falling back to HTTP mode.
Feb 19 00:35:28 freshclam[7977]: Current functionality level = 44, recommended = 58

I've deleted squid. Now HAVP works as transparent proxy.

clamd –debug

@goliy:

Something news:
Feb 19 00:31:12 clamd[11486]: MaxThreads * MaxRecursion is too high: 25500, open file descriptor limit is: 11095

Possible change /usr/local/etc/clamd.conf :

# daemon
MaxThreads                10
# scanner
MaxDirectoryRecursion     100

Then test new.

[goliy]

I'm sorry, but I am compelled to postpone the tests until I decide the main problem - with packets loss (http://forum.pfsense.org/index.php/topic,33467.msg173515.html)
very thx

[goliy]

Do you speak Russian?
My previous error was associated with the overflow table sizes. I fixed it.
Now it works, but the logs written some suspicious messages, like this:
Feb 24 10:36:19 havp[27558]: accept() failed: Software caused connection abort
Feb 24 10:34:47 havp[27586]: accept() failed: Software caused connection abort
Feb 24 10:34:43 havp[27803]: accept() failed: Software caused connection abort
