OK, I got a nasty surprise today. The server threw everybody out of the pool
and logged this:
10.224.12.4(52763) idle: pthread_mutex_lock.c:80: __pthread_mutex_lock:
Assertion `mutex->__data.__owner == 0' failed.
:4d45a006.78ec:2011-03-07 11:57:45.316 EST:LOG: server process (PID 21298) was
terminated by signal 6: Aborted
:4d45a006.78ec:2011-03-07 11:57:45.316 EST:LOG: terminating any other active
server processes
It then stopped all the backends, restarted, recovered and worked fine for the
rest of the day.
The particulars:
SLES 10
PG 8.4.1
8-way Intel Xeon E5345 @ 2.33GHz
32 GB RAM
max_connections = 1500
shared_buffers = 1536MB
work_mem = 32MB
maintenance_work_mem = 256MB
checkpoint_segments = 2048
effective_cache_size = 20GB
effective_io_concurrency = 6
random_page_cost = 2.0
This server has been rock solid running 8.4.1 for over a year. It has Slony
replicating to another mirror image server that has not had any problems
whatsoever.
Any ideas?
Thanks in advance for all your help, and especially for the amazing database
software!
Regards,
Bob Lunney
