I watched logs and in the /var/mail/postgres and I've seen this error that matchs in time with system crash. pg_dump: ERROR: invalid memory alloc request size 18446744073709551613 regards Enrico -- If Bill Gates had a penny for everytime Windows crashed,he'd be a multi-billionaire by now .......oh look, he already is !!!! scotty@xxxxxxxxxxxx - Skype:sscotty71 http://www.linuxtime.it/enricopirozzi
