Hi Jan,
I shall try to reproduce the lockup with -d2 debug level but, I am not sure this
is the only
lockup problem as it seems far to frequent twice today already and thats in only
4 hours of use :(
Q1. When a system task on a client gets killed how long is it before the database
releases it's record locks ?
Q2. When the Postgres server is shutdown and re started shouldn't all the record
locks have been removed ?
This situation seems to be getting worse, now I am scared to leave the building.
Regards, Frank.
