Hi!

Can urchin really spike the cpu iowait, load is 60-90 and you
can't work with the server at all.
When I chmod /home to 400 it is ok again.
So I figure it's writing a lot of stuff to /tmp o fthe users directories.

When I put it back it takes 1-2 minutes and it's back.
I'm starting to belive it's urchin that is the little sucker in the issue.

Can this be true ?

I killed urchinweb and removed urchin from statsselection in WHM (which I never had before but after an upgrade of cpanel it's turned on !!!!!?)

Go on, have a guess
Well, any web stats application is going to be IO intensive by their very nature. If you have an issue with it you need to speak to the urchin developers since it has nothing to do with cPanel.

I understand that Urchin is not cPanel but cPanel is so related to all thirdparty programs in how it's installed and tweaked.

I do understand, really, but your way would actually delete 50% of all the posts
in the cpanel forums. All post about Horde, Mailscanner, Mailman, Exim etc -
they actually doesn't belong here, correct ?

I would hate if these kind of posts dissapeared from this forums since it's
the best way of finding and asking for solutions.
I think all features and programs that cPanel is involved in, in one way or another,
belongs in this forum.

But thats my opinion.

Regards, Jerry

like what chirpy said, all stats program will definitely be IO intensive. You should learn how to "tweak" them to make less impact on your server. For eg, turn off some of the stats that you don't need, be it webalizer or awstat or others.

If your site is very busy, you would need to process your urchin stats like every hour. This would minimize long period of heavy load for daily process.

Try going to performance settings in urchin and set the "Urchin Run Priority" to LOW. Increase memory usage so that is runs faster.

You have misunderstood what I have said. The best place to ask for help if you're having performance problems with an application such as urchin is with the urchin developers site. Since there is practically no integration of urchin with cPanel, they are in the best place to help, especially since urchin is licensed through the urchin developers and not through cPanel.

I completely agree that people are free to talk about the applications that are components of cPanel, but urchin isn't one of those and so this is not the best place for that discussion, hence my referral to the developers of urchin that are being paid a license fee to support you.

Yes, I missunderstood Chirpy.
I thought you were saying like: go away, it's not cpanel issue.

Thanks for always answering most of everything by anyone,
your knowledge is appreciated.

By the way, Urchin is in the cpanel stats selection, tweak settings etc.
