Apache configuration files not building due to errors in configuration templates.

[DjFarout]

Hi, I've been getting the errors randomly for awhile. I would have to reboot the machine to get the sites working again. But now its happening more often. Could be, because we are adding/modifying more website info.

I ran through a few of the solutions on the KB site. The only thing it came up with, is Missing keys and column issues. Could this really be causing my problems?

I'm running
OS Linux 2.6.18-194.26.1.el5xen - (CentOS 5.8)
Panel version 10.4.4 Update #32.

Any thoughts?

Hi,

And what did you receive by email ?

 

[DjFarout]

This is what I got.

Generating new Apache configuration on host <server.com> failed because the following error(s) occurred:

Can not restart web server: httpd stop failed
0 /usr/sbin/httpd processes are killed
Service /etc/init.d/httpd failed to start
httpd stop failed
0 /usr/sbin/httpd processes are killed
Service /etc/init.d/httpd failed to start


Please fix error(s) in templates of Apache configuration and retry generating the configuration file.

Hi,

According to parallels kb, there are two or three reasons behind the error " Apache web server were not built due to errors in configuration templates". Did you tried each of the steps in the below kb ?

Ok, I tried all the linked items and they still didn't help. None of them really had the same symptoms. The issue seems to be with httpd not restarting.

2 ways I've gotten the server to come back are:

running "/usr/local/psa/admin/bin/httpdmng --reconfigure-all" several times or Clicking on the Regenerate button in the admin error log

OR

Restarting the server.

Or a combo of the 2.

IgorG - Do you have any other suggestions?
