Can any one please explain this to me?

I got it from "Cron <root@www> run-parts /etc/cron.daily"


NOTICE: Rel pg_class: TID 2/5: InsertTransactionInProgress 678696 - can't shrink relation

The error you are getting is a postgresql error. It happens when you vacuum a database or do allot of queries in a short period of time which overloads the db. It usually causes run away processes. As far as I know, there are no know fixes yet.

That's bad... :(

Hope I never got a second one regarding this...
