I am getting the following errors in syslog and clamd (clamav-daemon) is being killed. This came up in a previous ticket some time ago, but not sure why it is now.

When starting clamav-daemon it says the following:

It runs fine for a while and then gets this:

Jul 12 07:00:32 mail systemd[1]: clamav-daemon.service: Main process exited, code=killed, status=9/KILL
Jul 12 07:00:32 mail systemd[1]: clamav-daemon.service: Failed with result 'signal'.

This is from syslog, if I need to look somewhere else let me know.

The old post is https://forum.iredmail.org/topic1043-cl … shing.html . I have not tried deleting bytecode.cld as im not sure if this issue is related to that, as well that ticket was from 11 years ago.

Re: Clamd exiting (killed)

How many memory does this server have?
We mention at least 4GB memory is required for a low traffic mail server in iRedMail installation tutorials, and clamav will take most memory. if no enough memory for clamav, it may be killed by kernel due to OOM ("out of memory") error.

Buy me a cup of coffee ($5) to support iRedMail:

Re: Clamd exiting (killed)

I completely forgot I posted this. Figured it out a day later, 2GB on the server but my swap was only 512MB. Upped that to 2GB and havent had a single problem out of it.

Sorry about that.
