Hi,

I've made the odd bit of noise about this on the list before, but I'm
repeating myself because this particular problem is inordinately painful
for me...

Running Clamav and clamav-milter (now the 20040204 snapshot, but this is
an ongoing issue) with sendmail 8.12.10, and I get regular problems with
ClamAV spawning huge numbers of child processes, and generally falling over.

To gove an example, I upgraded to the CVS snapshot this morning, with
clamav-milter 0.66k, and started the daemon at about 11:30:-

Feb  5 11:34:42 castor clamav-milter[790]: ClamAV version 'clamd /
ClamAV version devel-20040205', clamav-milter version '0
.66k'

The first problems showed up just over an hour later:-

Feb  5 12:39:54 castor clamav-milter[10759]: hit max-children limit (5
>= 5): waiting for some to exit
Feb  5 12:40:28 castor clamav-milter[11254]: hit max-children limit (5
>= 5): waiting for some to exit
Feb  5 12:40:54 castor clamav-milter[10759]: ClamAv: private data not NULL
Feb  5 12:41:28 castor clamav-milter[11254]: ClamAv: private data not NULL

This carries on until I notice, and restart it. In an hour, it had got
to this:-

Feb  5 13:23:42 castor clamav-milter[16550]: ClamAv: private data not NULL
Feb  5 13:23:43 castor clamav-milter[16567]: hit max-children limit (136
>= 5): waiting for some to exit
Feb  5 13:23:46 castor clamav-milter[16572]: hit max-children limit (136
>= 5): waiting for some to exit

The number of processes grows beyond the max-children limit, though at
least some of them die, as the actual process count doesn't keep pace
with the logged number.

While it's in this state, messages aren't virus checked, as sendmail
just waits for the milter to time-out, and then gives up on it. I've had
these problems since I installed ClamAv, about 4 1/2 months ago. They
used to result in it going belly up every 2-3 days, but they seem to
have got worse - I now rarely get more than a couple of hours "life" out
of it.

I'm happy to provide any more information if it would help, but I'm
seriously considering uninstalling it at this stage - it's only working
about half the time because of this, and it causes mail slow downs the
rest of the time, while sendmail waits for the timeouts. Surely I can't
be the only person experiencing this - I'm not running anything that
weird and wonderful?

Mike.
