I am hitting my head agains wall - and witnessing strange behaviour, where after time most of load focuses only to one thread. I am not sure what is the cause of this, but so far we have seen different things before load has concentrated to one single thread.

After reading thread:

I started to wonder whether that signalling behaviour is also a cause for our problems - since we are running Debina linux without NPTL (
Linux 2.4.26 #1 SMP Thu Apr 22 11:16:14 EEST 2004 i686 unknown ).

When zope is started, it nicely starts multiple threads and when tested with ab - each thread gets their share of the work. We saw in event log previously exceptions that were never caught - and thought if those were the source of the problem. Eventhough we added ugly try catch code around this problematic code - we still notice load concentration to this one thread.

I will try to go and look with gdb those no longer working threads - but would like to know if anyone could give any pointers on what to look for or what to check.
