I have a PGSQL 9.0.1 database which is on the back-end of an app I was stress testing last night. This morning, when I try to run psql, I get:
psql: FATAL: out of shared memory
HINT: You might need to increase max_locks_per_transaction.
I believe something in the app is failing to release resources -- maybe a 3-way or 4-way deadlock between writing to tables inside the triggers in PGSQL or a deadlock between multiple processes talking to the app and the database or something leaking in the app itself which is causing locks to not be freed.
How do I track down what is going on if I cannot even run psql to get into the DB to run troubleshooting queries?
Thanks in advance for any suggestions.
