Hi,


I read somewhere that after the execution of the command sh ./clamd_fix_100_cpu_usage and when the system is restarted, the problem is restored ...?!?

Thanks in advance!

Edit /usr/lib/systemd/system/clamd.service

Code: [Select]
[Unit]
Description = clamd scanner (%i) daemon
Documentation=man:clamd(8) man:clamd.conf(5) https://www.clamav.net/documents/
After = syslog.target nss-lookup.target network.target

[Service]
Type = simple
ExecStart = /usr/sbin/clamd -c /etc/clamd.d/amavisd.conf --foreground=yes
# Reload the database
ExecReload = /bin/kill -USR2 $MAINPID
Restart = on-failure
TimeoutStartSec = 420
IOSchedulingPriority = 7
CPUSchedulingPolicy = 5
MemoryLimit = 768M
CPUQuota = 25%
Nice = 19

[Install]
WantedBy = multi-user.target

Code: [Select]
systemctl daemon-reload
systemctl restart clamd

I had the same problem, only this solution solved it for me. Now calmd runs with MAX 512M and taking 50% of 1 of 2 cores, so server is running smoothly. Thank you cynique!

swap/disk usage will be increased if you've it.

You are very welcome.

Let's see: unstable/unusable server or correctly uses swap where required. hmmm.  ::)

Do you know a better solution for this when the FIX script provided by CWP doesn't work? I'll appreciate that!

You should wrap the above in CODE tags. ;)
Note that I tested quite extensively and if you drop values too low, they simply get ignored.
512M/25% seemed to be a good balance, for most 'lower-end' server/VPS specifications.

DONE!

Thanks for the update. For now, seems like it's working fine like that, but I'll keep an eye on it!

Run the fix in the /scripts directory, and then log into the admin panel and manually STOP ClamAV & AMaViS.

After CPU goes down to 0%, Start Just ClamAV, wait for it to run a quick scan, it should go back to 0, then Start AMaViS.

You should be good to go.

Had the same problem, and this worked.
