You mean it crashed?
Please provide excerpts of /var/log/clamav/clamav.log and 
/var/log/syslog from around the time of the crashes.

If you can reproduce the crashes, please install clamav-dbg and use gdb 
to provide a backtrace of the crashes.

Again, please provide the logs mentioned above.

Please set 'Debug true' in /etc/clamav/clamd.conf, restart clamav-daemon 
and provide debug logs, when the issue happens again.

Best regards,
