Package: clamav
Version: 0.103.10+dfsg-0+deb11u1
Severity: important
Hi,
I'm scanning incoming mails using clamav-daemon and clamav-milter.
From time to time, my mailserver stops working due to clamav-daemon locking up.
The clamav logs read:
6889 Apr 25 11:28:12 gate clamd[939931]: Thu Apr 25 11:28:11 2024 -> !accept() failed: Too many open files
1 Apr 25 11:32:11 gate systemd-journald[311]: Suppressed 490085 messages from clamav-daemon.service
(with many repetitions)
1 Apr 25 11:33:41 gate clamd[939931]: LibClamAV Error: cl_engine_addref: engine == NULL
1 Apr 25 11:33:41 gate clamd[939931]: Thu Apr 25 11:33:41 2024 -> !cl_engine_addref() failed
1 Apr 25 11:33:41 gate clamd[939931]: Thu Apr 25 11:33:41 2024 -> !Command dispatch failed
(with many repetitions)
Workaround: systemctl restart clamav-daemon fixes the problem temporarely.
