Hi,
Well ... almost identical ... yes, I know, that does not count with computers.
Upgraded to FreeBSD 8.1 did not fix the issue.
Upgraded to Perl 4.12 did not dix the issue.
So I removed all mails from the queue ... and let it run for a while
with Virus disabled all the time.
And seem to do the trick ... I havent testes yet with Virus scanner
enabled and some 3 part SA rules.
But I will let you know if I can reproduce the problem ... right now
I'm just happy the system runs again.
Still ... the odd thing is that is just started to crash ... so maybe
a speciel "clamd" rule made it crachs sometimes ...
But one thing I tried, not sure if its anything I need to be scared
about is this:
truss -p 3000 ( the process id )
Gives me this:

Make a notice of the ERR# messages in the above output ...
ps ax | grep "MailS" show me that the MS processes was waiting to
deliver Uninfedted messages ....
When running "top" ..... the State of the processes was "fifoow" and
someone told me it was a locking issue ... :-s
But ... I'm still investigating things ... but if anyone got ideas ...
do please let me know.
Thanks
