Maybe the problem is using only one call signal handler to handle the load. Try to increase CallSignalHandler to a greater value and see if it still happens.

Under high load latest 2.0x GnuGK crash. We got crash every day or sometimes every 2nd day (always only under high load / mean > 1E1)
Linux RedHat9. GnuGK compiled with latest OpenH323 + latest PWLib. GnuGK was in routed mode without full proxy (only signaling was pass over it, no RTP channels).
It was have around 2E1 load or 60 active calls. CPU = Intel 2.4 GHz with load less then 5%. RAM = 512 mb (most free).
Nothing special in INI (CallSignalHandlerNumber=1). Total minimized binary compiled with no radius, no accounting, no mysql. Was used GCC version 3.3.5 for compilation. CDR's was collected over 7000 port. No any commands or reloads over 7000 port.
Calls pass in GW-GW mode over single predefined in INI permanent endpoint (no ARQ, no LRQ - all calls was go between 2 fixed CISCO AS5300 IP's and start from Q931 setup)
Crash call stack:
Gatekeeper::Main()
Gatekeeper::HouseKeeping()
H323RasSrv::Check()
HandlerList::Check()
ProxyHandleThread::CloseUnusedThreads() (this=0x4022c5d0) at ProxyThread.cxx:740
MyPThread::Destroy() (this=0x40269bd8) at thread.cxx:56 (called from ProxyThread.cxx:761)
PThread::WaitForTermination() const (this=0x40269bd8) at tlibthrd.cxx:1198
PThread::IsTerminated() const (this=0x40269bd8) at tlibthrd.cxx:1183
pthread_kill () from /lib/tls/libpthread.so.0
Look like ProxyHandleThread::CloseUnusedThreads() code in not thread safe. Can anybody comment how to solve this and make it stable ?
