Hi,
I was running a manual vaccum through pgadmin 1.4.1 on a database and my connection to the database was lost during it.
I reconnected to the database, went to Tools->Server Status->Log File and there is an entry that says:
"This application has requested the Runtime to terminate in an unusual way. Please contact the application's support
teamfor more information".
I am running XP Pro SP2. Database is 8.1.1 and is not located on the same machine.
I also have autovaccum enabled.
Would be happy to give more information if I can.
Mike
