Hi all,
I have a problem about deadlock. I have several stored procedures; only
one of them uses ACCESS EXCLUSIVE LOCK on a table; however, all the
stored procedures can access to that table, using SELECT, INSERT or UPDATE.
The stored procedures are called by different processes of an external
application.
In a non-predictable way, I obtain error messages like this one:
2005-11-29 18:23:06 [12771] ERROR: deadlock detected
DETAIL: Process 12771 waits for AccessExclusiveLock on relation 26052
of database 17142; blocked by process 12773.
Process 12773 waits for AccessExclusiveLock on relation 26052 of
database 17142; blocked by process 12771.
CONTEXT: PL/pgSQL function "set_session_box_status" line 7 at SQL statement
I don't understand what's happening; is it possible that a deadlock is
detected on the same relation (that is, the stored procedure using the
ACCESS EXCLUSIVE LOCK mentioned before) ?
I'm using Postgres 7.4.7 on a Debian Sarge.
Thanks!
Francesco
