Hi all,
I am running Tomcat 4.0.24 on Red Hat Linux 7.3, I installed it from the
jpackage RPM a few months ago.

Tomcat worked fine until this morning, when I upgraded the control panel
server (SWsoft Plesk) for the server to a new major version (5.0.5 to
7.0.2).

The problem is that Tomcat doesn't start anymore as user "tomcat4", it
starts fine as user "root", I am using the script /usr/bin/dtomcat4 to
launch it. (I don't like the idea of running Tomcat as root!)

The control panel upgrade procedure did a few tasks on the server and I
not sure what broke my Tomcat installation.

I cannot figure out what's wrong and log files are not helping much
(check out below), I took a quick look at tomcat files/directories
permissions and they look fine to me, but there may be something wrong
that I am missing ...

Any idea?

Here is the content of the file catalina.out from a successfull start as
"root":
