Hope this won't look too garbled. sp_who2 shows a bunch of processes from 10/18. Checking the sql error log, I see that was after a server restart on the same day. The server has been restarted once since then (2/24), but I do not see any processes with that date.
Would the CHECKPOINT in this list be significant?
