A customer has an MSDB instance that is about 140GB. The problem is a monster message queue w/ over 70 million records. It's for a 3rd-party tool they haven't used in years.
Like this, only several times bigger: http://www.sqlservercentral.com/Forums/Topic883785-146-1.aspx
I have not been able to disable broker on MSDB b/c we can't put MSDB into single-user mode on weekdays. May try that tomorrow.
But when I run the DROP SERVICE statement (which attempts to empty the queue), the TLog grows to fill the disk. Last night it ate nearly 500 GB before being out of space and rolling back.
The entire MDF is about 140 GB. But TLog for dropping this service wants over 500 GB. They're talking about attaching a 1TB USB drive, but I don't know whether that would be enough either!
How much space should I expect it to take? And is there another way? I've been over the documentation and all I'm sure of is that I can't TRUNCATE the QUEUE -- which is what I'd really, REALLY like to do.
