Suddenly 99.8 % clamd.virtualmin -c /etc/clamd.d/virtualmin.conf

Help! (Home for newbies)

Hi People,

Suddenly and without any warning I find that the server is running very slow and I see that clamd.virtualmin -c /etc/clamd.d/virtualmin.conf is using 99% of the processor.

This server is very lightly loaded and handles about 100 emails per day.

I have read loads of posts about clamscan, clamd and clanc but can’t really say that I understand what is happening so perhaps I need some hand-holding with this. (sorry !)

When I look at “system Information” page (the one that shows immediately upon login) it says :-

Running processes 137
CPU usage 20% user, 5% kernel, 0% IO, 75% idle

If I click “Refresh system information” the page never seems to update, If I exit and re-enter the server it shows the same CPU usage but maybe one extra or less process running.

The server showed two packages to update (tzdata-java and tzdata) I updated them but the system Information page shows them still to update. If I try to update I get the error/warning that all is up to date.

CentOS Linux 5.11
Webmin version 1.821
Virtualmin version 5.04
Kernel and CPU Linux 2.6.18-412.el5 on x86_64

I have another server of very similar spec showing the same.

Any help would be well appreciated.

Thanks for reading,
Tim

I have continued to fight this but perhaps I really am not looking in the right area.

I thought that if I could stop virus scanning then clamd would stop and I could at least get some sensible processor use. So I attempted that through “System Settings” > “Features and Plugins” but relieved the warning that sites were using it. I disabled anti-virus on those sites and tried again. but still received the same error (sites using anti-virus), I checked the actual sites (all 11 of them) but they are shown as not running AV.

Thanks for reading and any insight you might have.

Came back in the vain hope that someone had replied (not that I have any right) but alas …

Anyway, I have now discovered that user authentication fails on outgoing mail.
