Yeah - we'd like to keep all users but it does seem to slow the system down once you get too many users. If we hadn't started deleting we'd have just under 400,000 users by now (we also need to import all "applicants" each year. most of which never even come here in the end).
We've found the same issue now for our Notes collection which has over a million records and becoming noticeably slow.
So until LanDesk has some form of built in archiving/housekeeping we need to rely on manually run scripts etc.
My SQL is pretty poor too (esp Oracle) but the script seems to be removing the process constraint before trying to delete the user, and has been working well for years - so we just wondered if anyone had any ideas why it would suddelny produce this error...
Cheers.
