Suspicious processes and Excessive Resources

FnF · Feb 14, 2013

Hi folks,
I recently had my data center update WHM/Cpanel to 11.36X and I've been getting flooded with hundreds of CSF emails a day now indicating Suspicious processes and Excessive Resources all related to webalizer for every account on my box, that I never got before.

My data center is suggesting trying increasing some of the process tracking directives for CSF.
I'm not understanding how updating Cpanel should require me to tame CSF so it's not triggered as easily. I like the warnings, I'm very paranoid, but I cant help but to think something is wrong since now that Cpanel has been upgraded I'm getting warnings off every site.

Wondering if someone could shed some light on this for me? I tried posting the same question on the CSF forums and not a sole will respond.

An example of the daily warnings that I get for each account on the server;
Excessive processes

put
exe:/usr/local/cpanel/3rdparty/bin/english/webalizer

into your csf.pignore

FnF · Feb 14, 2013

Thanks much dalem, but does that mean it was being ignored before I upgraded Cpanel?
At the risk of looking like an idiot, my fear is wondering why it's a problem now.

quietFinn · Feb 14, 2013

You can't ignore something that does not exist, i.e. /usr/local/cpanel/3rdparty/bin/webalizer_lang/english did not exist in earlier version of cPanel/WHM.

FnF · Feb 14, 2013

Ahhhh

That makes perfect sense. Thanks so much, both of you. I appreciate your patience with me.

dalem · Feb 15, 2013

yes it should have been exe:/usr/local/cpanel/3rdparty/bin/webalizer_lang/english

the 11.36.0 changed the webalizer loc

we got them to

southbay · Mar 14, 2013

I have begun receiving the same alerts from lfd & found this thread. Attempting to follow the suggestion of inserting exe:/usr/local/cpanel/3rdparty/bin/english/webalizer in the csf.pignore file, but that line already exists! Now what?

Infopro · Mar 14, 2013

What exactly does your email say?

quietFinn · Mar 14, 2013

Shouldn't it be:
exe:/usr/local/cpanel/3rdparty/bin/webalizer_lang/english
instead of:
exe:/usr/local/cpanel/3rdparty/bin/english/webalizer
