Hi,
thanks a lot for the immediate answer, I also changed the code immediately, and
started another long-term test run.
Just found the process 99% busy again - the good news is that the signal pipe
does not seem to be the culprit :-).
Any other suggestions are highly welcome ...
Thanks & best regards,
Markus

This sounds very familiar to me.
I encountered a similar problem on solaris and was able to make it stop by
putting the following line of code at the beginning of my POE program:
BEGIN { eval "sub POE::Kernel::USE_SIGNAL_PIPE () { 0 }" }
There seems to be a problem with the signal pipe on some platforms, but I
haven't yet done more research to track down what's going wrong.
