[rt-users] webmux.pl causing Apache to fail

[Alex Young]

Thanks for this. Turns out MySQL wasn't accepting connections. Our
monitoring system wasn't picking it up as MySQL was still running. 

I havent used the Ubuntu package for RT in a long time. I have been
happy to install RT manually into the defult location along with RTFM
and RTIR, and figure if a new update comes out that would be handy it's
a lot easier to just upgrade RT as needed, rather than relying on a
package maintainer to update it.

First, is there any reason not to use the stock request-tracker3.8
package available in Ubuntu? Does it have the same error?

Otherwise the only idea I have is that the DB backend configured for
your RT instance is unavailable at the time apache starts because what
webmux.pl does, among other things, is connecting to the specified DBMS.
We had a bug with similar symptoms in Debian [1]. In my case, apache
failed to start after waiting for a timeout due to inaccessible MySQL
server; may be your case is similar just the timeout is not triggered
for some reason.
