i am doing some cleaning and i really need to delete it but i keep getting this error.

i even increased the innodb_lock_wait_timeout from 50 to 100 and it still not doing the job...

& i have plenty of ram allocated...

it even crashes when i try to delete a node with 7 Children

When a forum is deleted, all of the child forums and threads within those forums are also deleted.

How many threads are there in the forums?

I think the children are actually being moved, which should be reasonably fast.

But this issue looks more like there has been a "double submit" -- trying to delete another node while the first one is still deleting. Most of the work of deleting is actually pushed out to a later job too, so the deletion process it self shouldn't be especially slow.

You may need to attempt again and if you get this error, run SHOW FULL PROCESSLIST; in MySQL to see what query is currently running.

i emptied the threads i moved them into other sections

it was only 50 empty forums.

in the end i was able to delete it. but i had to delete it piece by peice as the whole thing wouldn't work for me..
