closure table when moving threads
 

I recently upgraded to vbulletin 5 from vbulletin 3.8

Our forum has literally millions of threads/posts. And now every time we try to moderate a thread (say, move it to a different channel/forum) it times out. I identified the problem being in the closure table (it has about 54 million rows) and the following query takes forever:

DELETE cl3 FROM closure AS cl
INNER JOIN closure AS cl2 ON cl2.parent = cl.child AND cl2.depth > 0
INNER JOIN closure AS cl3 ON cl3.child = cl2.child AND cl3.parent = cl.parent
WHERE cl.child IN (873064) AND cl.depth > 0

Any suggestions on how to go about fixing this problem? Thank you!

Hi.... I've got the same problem.... Have you found a solution?

Did you update to the most recent version of vBulletin 5 yet?

Sure... we made 2 days ago UPGRADE with VB service..... with Joe...
