web project doesn't start anymore

I have an installation that was working fine.
Today I did an update, which resulted in an ‘Internal Server error’
The project is running on a Linux Centos 2.6.32-573.7.1.el6.i686
In the logfile /var/log/messages I found this:

Installed this:

Does anybody knows what that means

Have you made sure to kill the current processes of that app ?

There are no processes, because there is no start.
As you can see in /var/log/messages, the webserver cannot start the project

In most cases it is some hanging process which I detect with
ps -ef|grep cgi

Must be something else
