Thank you.

The issue is mega threads slow vB down and can indeed lead to database corruption, as I understand the issue. E.g. I notice when working on these threads I get errors and unexpected slowness affecting different operations. The lengthier the thread, the worse it seems (I speak anecdotally because I haven't documented and measured formally.)

Moderators have been instructed to pare these mega threads near the beginning of the year, and in different fora this might be handled somewhat differently.

Whether this is done by closing a thread and starting a new one, archiving off older posts, etc. the end result is more manageable threads. These days, wikis make the transition easier, so we often transfer (and may update) wiki contents to new threads on the same topic.

Perhaps one of our Admin reps can expand.
