CPanel Impad Process
Jun 15, 2007
I'm running Fedora with cPanel.
Every day, at around this time, there is an impad process for a specific user that seems to run for hours and takes the load beyond 1.2 . Whenever I kill this process, a new spawns off (see below).
ps aux | grep user :
user 31570 98.6 0.0 3184 720 ? R 11:00 1:53 /usr/lib/courier-imap/bin/imapd /home/user/mail/userdomain.com/user
user 31573 0.0 0.0 2932 708 ? S 11:00 0:00 /usr/lib/courier-imap/bin/imapd /home/user/mail/userdomain.com/user
root 31847 0.0 0.0 5320 612 pts/0 S 11:02 0:00 grep user
why the mailer is doing that for this particular user?

Recently, there are a lot of "apache" processes hogging my Cpanel server with the default owner "nobody". How could I track the apache process back to which user is using it?

Right now I am using the built-in cpanel backup feature to backup all the accounts on my server to an offsite FTP backup account I have on a weekly basis. The problem I am having is that everytime the backup runs, the load (thats what I'm guessing is the cause) is crashing apache/bind, causing sites to be unreachable until I can restart the services. What options do I have to resolve this issue? Currently I already have spri installed, and it does help out a bit, but its still not enough.

Mysql server is taking 256mb, there are somewhere between 6 and 10 apache process taking up at least 40mb each.
Furthermore, when I do: top, I see that the memory usage is increasing by about 120ko each 3 sec.
I am running centos 5.1 and have a load of 0. Basically, there is no one on the server appart from me.
On the server I have at home running debian, I run all thoose thing and it take up 200mb

write me a daemon that will run every 10 seconds.
If <process> has failed or run into issues, restart the process and then email me with details.
After installing LiteSpeed on my server with cPanel, a few processes have been having issues.

I'd like to put up here a base question which I hope some will have the goodwill to answer even though it might touch some business secrecies.
We're a gameserver hoster since around ten years, running also vserver products since over two years now. Renting a few Racks in Europe since some time we're a bit in a question mark how rootserver companies deal with the initial hardware costs for every new customer.
Rackspace and today specially power costs are huge cash eaters here in Europe. Dedicated Rootservers are huge space & power consumers per customer ratio. The initial Hw costs for every new rootserver customer might be covered after 4-6 months (if the machine has to be bought newly), adding the bandwidth and power costs it might take up to 8-9 months until a benefit might come in.
Is this the business normality in the rootserver market (waiting 9 months for any benefit, or counting only on the benefit of the 2nd customer using the older Hw), or are the better ways to handle those "initial" costs or keep them affordably low?

My hosting company is telling me that I have getting frozen processes on my VPS that is causing apache to stop responding.
My VPS is CentOS, with 512 megs of memory and my website is a Vbulletin forum. I have several add-ons installed on vbulletin, and if one of those are causing the problem, how do I figure it out?
When http stops responding, I can access the server with putty on ssh. Running the "top" command, it shows that I still have 100+ megs of memory free and the processor is barely being used.
This has happened twice in just 2 - 3 days. This morning, I asked my hosting company what can be causing this, but no answer so far.

I run a dedicated server, Running
CentOS 4.5 final
Apache 2.0.59
php 4.3.11
MySQL 4.1.20
I have a user who has been importing large sql databases and this causes the cpu to run at 80% - 90% this in turn causes high loads and sometimes causing the server to crash.
Is there a way to automatically limit or control how much the process can use or stop the process to allow the server to recover.
Just trying to put some sort of safe guard in place
