Hi, I noticed Clamd has unexpectantly died on two of my virtual machines. Investigating lead me to find similar errors in the logs on both hosts around the times I know clamd died (I'm monitoring for the existence of a clamd process with zabbix but only got around to investigating today due to other commitments)
System1 Virtual Machine CPU : 1 socket / 2 cores RAM : 2GB Ram (I must have been feeling frugal on the day I created that VM) OS : Debian 10 / buster Clam : ClamAV 0.103.5/26484/Thu Mar 17 08:28:38 2022 Mar 13 13:14:27 System1 clamd[9495]: LibClamAV Warning: fmap_readpage: pread fail: asked for 901703 bytes @ offset 4096, got 0 Mar 13 13:14:27 System1 clamd[9495]: LibClamAV Error: fmap_get_MD5: error reading while generating hash! Mar 13 13:14:27 System1 systemd[1]: clamav-daemon.service: Main process exited, code=killed, status=11/SEGV Mar 13 13:14:27 System1 systemd[1]: clamav-daemon.service: Failed with result 'signal'. System2 Virtual Machine 1 socket / 2 cores 4GB Ram (This is our standard allocation; This VM isn't in production yet and isn't doing anything) OS : Debian 11 / bullseye Clam : ClamAV 0.103.5/26484/Thu Mar 17 08:28:38 2022 Mar 9 19:56:17 System2 clamd[541]: LibClamAV Warning: fmap_readpage: pread fail: asked for 455239 bytes @ offset 450560, got 0 Mar 9 19:56:17 System2 clamd[541]: LibClamAV Error: fmap_get_MD5: error reading while generating hash! Mar 9 19:56:17 System2 kernel: [19292.532221] clamd[6494]: segfault at 0 ip 00007f73de568a08 sp 00007f73777fd410 error 4 in libclamav.so.9.0.5[7f73de491000+11d000] Mar 9 19:56:17 System2 systemd[1]: clamav-daemon.service: Main process exited, code=killed, status=11/SEGV Mar 9 19:56:17 System2 systemd[1]: clamav-daemon.service: Failed with result 'signal'. Mar 9 19:56:17 System2 systemd[1]: clamav-daemon.service: Consumed 20min 43.611s CPU time. This feels like it could be related to a lack of RAM? Would anyone be able to confirm I'm on the right track before shutdown the VMs to I allocate Ram?
