vBulletin timeout when move thread from one channel to another

[[email protected]]

Hi there,

I have two channel in my forum, channel A has 100 post, channel B has 50,000 posts, when I move topic from A to B, the ajax call "moveTopics" hanging there over 1min and return timeout error, however the post got moved successfully. I have track down the slowest operation in here /core/vb/library/node line 88

public function clearChildCache($nodeids)
    {
        $childrenArray = $this->fetchClosurechildren($nodeids);
        $events = array();
        foreach ($childrenArray as $children)
        {
            foreach ($children as $child)
            $events[] = 'nodeChg_' . $child['child'];
        }
        vB_Cache::allCacheEvent($events);
    } 

where the $childrenArray return around 50,000 result becasue the $nodeids contain my moved topic nodeid and channel B nodeid, then the script just un-response at vB_Cache::allCacheEvent($events);

Also I'm using memcache, when I switch to db cache, there is no error.

Can you raise your findings in the Tracker for our developers to look at - they rarely check the forums so would be easier to have it picked up there...

The only workaround is to move fewer topics at a time.
