[TRAFODION-3225] Obscure cores seen in RMS and logger related code whâ¦
â¦en Trafodion is stressed
Process de-registration is now logged to understand the spate of cores seen
during
stress testing
Cleanup dangling semaphore incorrectly detected the problem due to pid
recycling and
hence de-registered the process and its query fragment from the shared
segment
When the RMS semaphore is held for more than 10 seconds, it is assumed to
be in a
deadlock situation and hence the process holding the semaphore is core
dumped for
further analysis.
Create a global logger instance instead of a function static variable
to help in debugging when problems with QRlogger is reported.
