OK, for some reason if I unload a loaded world, the server *sometimes* crashes. Its the evil

PHP:

getChunk() on null

Error .........

I tried kicking everyone on the map and removing all the entities - and doing nothing. It still crashes #Somtimes !!! This is also a common problem apparently (#ManyWorlds)

Any way to fix dis? Thanks

I would also like to hear a way to fix this.

I believe it is an issue with pthreads or other parts of PHP binaries.

You could just add if null then $world = world or stuff. I guess this works.

Maybe because you are trying to unload a null world. Check your values before passing.

It's the fault of the Owner of the ManyWorlds plugin, he must set a default value when worlds are null, so the process aborts itself or something.

No and no.

This is the code that does the unload:

PHP:

      if (!$this->getServer()->isLevelLoaded($level)) {
         $sender->sendMessage("[MW] Level $level is not loaded.");
         continue;
       }
       $world = $this->getServer()->getLevelByName($level);
       if ($world === null) {
         $sender->sendMessage("[MW] Unable to get $level");
         continue;
       }
       if (!$this->getServer()->unloadLevel($world,$force)) {
         $sender->sendMessage("[MW] Unable to unload $level.  Try -f");
         continue;
       }
       $sender->sendMessage("[MW] $level unloaded.");


So actually, it does check if $world is null. Also, it is only calling the API unloadLevel method.

What is more problematic is that I can't consistently get the error. In fact, right now, I have been unloading levels willy nilly without crashes...
