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. -- Package-specific info: --- configuration --- Checking configuration files in /etc/clamav Config file: clamd.conf ----------------------- AlertExceedsMax
