[clamav-users] clamav-daemon crashing periodically

[Jesús Arnáiz]

Hi!

I have an Ubuntu server as email server. I use there, MailInABox:
https://mailinabox.email/

I installed on my own (since it is not part of MailInABox) clamav and I 
configured it to be used with clamsmtp on postfix, so email is scanned 
for virus.

It normally works fine, but, apparently it is crashing everyday more 
than once, meaning a manual restart is needed once or twice per day.

I don't see anything relevant on the logs, more than error of clamsmtp 
complaining it "can't connect to clamd" (expected issue if the service 
is stopped as is the case):

---
Jun  3 08:42:54 mailbox clamsmtpd: 10126F: CLAMAV: couldn't connect to: 
/var/run/clamav/clamd.ctl: Connection refused
Jun  3 08:43:32 mailbox clamsmtpd: 101274: CLAMAV: couldn't connect to: 
/var/run/clamav/clamd.ctl: Connection refused
----

A manual restart makes the error disappear and it continue working for a 
while.

For the moment as a temporal workaround, I set some crontab to check the 
"clamd" process and restart it if it is not running. But I would like to 
find the issue and fix it if possible.

Any ideas?

My system is:

----
Linux mailbox 5.3.18-3-pve #1 SMP PVE 5.3.18-3 (Tue, 17 Mar 2020 
16:33:19 +0100) x86_64 x86_64 x86_64 GNU/Linux

Ubuntu 18.04.4 LTS

ClamAV Version:

clamscan -V
ClamAV 0.102.3/25831/Tue Jun  2 14:41:03 2020

CalmSMTPD:

clamsmtpd (version 1.10)
           (config: /etc/clamsmtpd.conf)


Thanks!,
Jesús.
