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 ...

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. -- Tod
