All,
I have a recently-migrated Pg cluster running 8.4.7 on Red Hat Enterprise
Linux Client release 5.7 (Tikanga) in a VMware VM that is logging the
subject warning. The application code is considerably old (deployed back in
the 7.4 days, I believe) and the message is preceded by a call to select
user_write_unlock(), which is a simple wrapper query that calls
pg_advisory_unlock(). What are the causes and possible problems and
side-effects of receiving such a log warning? Thank you for any assistance
you can provide.
