Recently, we've started seeing cases where merging tickets can create a loop in WHD, causing the whole system to slow to a crawl and requiring a reboot of the server to resolve (albeit temporarily).
What can trigger this appears to be merging ticket 1 into ticket 2, and then trying to merge ticket 2 into ticket 1. It seems that the ticket merging isn't being confirmed well enough, causing the user to think that the tickets weren't in fact merged, even though ticket 1 might end up being closed.
Even if ticket 1 ends up being deleted to break the loop, some tickets aren't noticed, and can cause loops in the SQL database, slowing down the system.
Has anyone else experienced these or similar problems with ticket merging in WHD?
