Lost connection to selected backend (proxyd -> imapd)

[Reinhard Proessler]

Right, Frontend Proxd crashed and I also do not believe that this is a 
physical connection problem.
The line is well monitored and not overloaded, not even under any "load".

After a "reconstruct" , which runs fine, the problem persists.

But an upgrade is not so easy. We use the original RPM package 
2.2.12-8.1 and upgrading
to 2.3.x means building a complete new package from next RH EL5.0 SRPM.
We have ~ six hundred users on our servers, direktly connected to the 
backend w/o problems  ;o)
