Hello,
I'm running clamav 0.965 on a G5 with OS X Server 10.4.11.
A launchdaemon automatically kicks off an overnight scan by sending a command
to clamdscan.
Starting last night, clamd began crashing while scanning a certain directory
(crash log at the end of this message).
Calling clamscan manually to scan that same directory runs successfully.
Nothing bad is found.
Clamd is running as root on this machine.
What is the most practical way to debug and correct this problem?
