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.

I have the same problem with a box with clamav (66k, cvs 20040204) and clamav milter, FreeBSD 4.9-STABLE , sendmail 8.12.10

The box is:
CPU: Intel(R) Pentium(R) 4 CPU 2.40GHz (2399.59-MHz 686-class CPU)
[...]
real memory  = 1073676288 (1048512K bytes)
avail memory = 1042358272 (1017928K bytes)

When the mail server stop working I have a lot of clamav-milter process hunged and the sendmail is unable to deliver. The last logs are:

Perhaps I should increase the MaxThreads=10 to something more (20, 50 ...) ?

cvs-src is built on a FreeBSD 4.9-STABLE with :
./configure     --enable-milter
                --sysconfdir=/usr/local/etc
                --prefix=/usr/local
                --with-dbdir=/usr/local/share/clamav
                --disable-clamav

Thanks...
