Hi there,

after I've been running MailScanner successfully since beginning of August,
strange things are happening since last Saturday.
Since then, MailScanner has started being killed from time to time (out of
memory) and thus begun starting inumerable processes making the system going
out of memory, the load climed dramatically (avg load > 16) and several
processes (i.e. apache, exim, shh, ...) exited and the system hung (log
excerpts see below).

Well this happend twice the last few days.
Has somebody a experienced similar beaviour or a glue what that might come
from?

I'm running MailScanner (4.32.5), with SpamAssassin (2.64), ClamAv-Module /
Bitdefender on a Debian box with exim (exact config below).

Any hints appreciated!
Thanks
