Thanks for the replies.

We take t-log backups every 2 hours, in full recovery mode. This vendor has been more difficult then most to deal with when it comes to their processing. We do index rebuilds nightly, but has no real effect on the t-logs. To say, after shrinking and running the process we don't have 192 gig log file, or anywhere near that. It has been steady at 8 gig for about the last month. So we'll keep our fingers crossed and see what happens next.

Thanks

Tom
