Re: Why will vacuum not end?

Josh, how long should a vacuum take on a 87 GB table with a 39 GB index?

I do not think that the verbose option of vacuum is verbose enough.
The vacuum keeps redoing the index, but there is no indication as to why it
is doing this.

I see alot of activity with transaction logs being recycled (15 to 30 every
3 to 20 minutes).
Is the vacuum causing this?

FWIW, I've had this happen a couple of times, too. Unfortunately, it's
happend in the middle of the day so that I had to cancel the processes and
get the system back to normal in too much of a hurry to consider documenting

it.
