SYMPTOM(s):
Database crashes after user terminates session abnormally
Database logfile shows errors (5029), (2522) and finally (2249)
SYSTEM ERROR: Releasing multiplexed latch. latchId:<latch-num> (5029)
User <num> died holding <num> shared memory locks. (2522)
Begin ABNORMAL shutdown code (2249)
FACT(s) (Environment):
HP-UX 11.0
Progress 9.1E
CAUSE:
A remote user said that part way through an update their terminal froze. As a "solution" they took it upon themselves to unplug the network cable and plug it in somewhere else. Consequently his session died.
The user still held a latch when he died, Watchdog picked up on it, released it and the broker subsequently shut down the database to protect its integrity.
FIX:
Do not terminate sessions abnormally like this.
