[clamav-users] 0.100.1 issues - allocation memory / pthread create failed

[Micah Snyder (micasnyd)]

If you are using clamd's on-access scanning feature, this may be a result of the issue with the "OnAccessExtraScanning" option that prompted us to disable extra-scanning in 0.100.2 (and the upcoming 0.101) until we have the thread resource issue with extra-scanning resolved.

Can't allocate memory ERROR

Looking to get help on the aforementioned errors.  On version 0.99.2
we had no issues but once we went to this version, we''ve processing
outages and only a server restart / unload would resolve the issue.
Any help would be appreciated, but the configs are basically default
aside from the advanced logging values we have set.  The servers are
never taxes nor does the traffic seem to peek when this occurs -
happens at random times but every few days.

Your description sounds to me like the sypmtoms of a memory leak.  To
begin with I'd put something like this

* * * * * /bin/date >> /tmp/clamstats.log ; /usr/bin/top -b -n1 | /bin/grep clam >> /tmp/clamstats.log

in the crontab.  It's unclear to me if ClamAV is the problem or not,
and this at least ought to tell you something.
