  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

URGENT: CPU and RAM spikes on clean install

markcarsonboxz

New Pleskian
I recently performed a clean re-image and install of CentOS 5.5 and Plesk 9.5.2

Each time I login and browse the Plesk Control Panel, the CPU and RAM usage spikes. Using Virtuosso, the list of processes contain:

13542 0.3 0.0 /usr/bin/sw-engine-cgi -c /usr/local/psa/admin/conf/php.ini -d auto_prepend_file=auth.php3 -u
13549 7.5 0.2 /usr/bin/sw-engine-cgi -c /usr/local/psa/admin/conf/php.ini -d auto_prepend_file=auth.php3 -u
13550 0.3 0.0 /usr/bin/sw-engine-cgi -c /usr/local/psa/admin/conf/php.ini -d auto_prepend_file=auth.php3 -u
13553 0.0 0.0 /usr/bin/sw-engine-cgi -c /usr/local/psa/admin/conf/php.ini -d auto_prepend_file=auth.php3 -u

Each of these have been as high as 25%, killing the VPS.

Any reason why this is occurring? (threads from old posts indicate a problem/bug in Plesk, but this was v8.3)
 
Looking through some logs, I found the following:

/sw_cp_server/error_log:

Thanks for the prompt reply. I did look at this post, but thought that the issue was too specific to that post.
I got a bit p**sed off and completed a reimage.
If this happens, I'll know where to look
 
Reimaged the server. Same problem with no updates applied - using version 9.0.1.

List of installation tasks completed:

Update existing php packages from 5.1.6 to 5.2.13
wget -q -O - http://www.atomicorp.com/installers/atomic.sh | sh
yum --disablerepo=centos* update php
Install php-mcrypt (resolving dependencies manually)
yum install libmcrypt
yum install libmcrypt-devel
ldconfig -p | grep libmcrypt.so.4
ls -la /usr/lib64/libmcrypt.so.4
yum install php-mcrypt.x86_64
Restart httpd process
/etc/init.d/httpd restart
Install other php extensions; required for later application installation
yum --disablerepo=centos* install php-tidy.x86_64

Install PCRE with Unicode Support
wget http://chrisjean.com/wp-content/uploads/2009/01/pcre-66-27x86_64.rpm
rpm -Uvh ~/pcre-66-27x86_64.rpm

Required at least PHP 5.2, with tidy and mcrypt.
Followed instructions from 1&1 to update php to 5.2.13 here
Researched and installed mcrypt from same location
Hopefully PCRE update hasn't broke Plesk!

The following httpd error appears to be fixed:

I have not completed any other configuration or installations tasks.

I would appreciate any comments or help with this.
 
More Information:
Kernel: 2.6.9-023stab051.3-smp (CentOS? Really?)
I attach a file containing all installed packages.
