Passing events

[MajikTom]

In addition to RegionJukebox, there are a few other plugins that keep failing to get events passed:
WormholeExtreme
BattleArena
There may be more but the errors are the same and cause PermGen memory exceptions:
java.lang.OutOfMemoryError: PermGen space

There is a workaround for those who can afford it and/or are able to customize their buckkit startup parameters:

in the java startup add this:
-XX:+UseConcMarkSweepGC -XX:MaxPermSize=128m
so an example for a 4gig environment would be:

java -Xms4096M -Xmx4096M -XX:+UseConcMarkSweepGC -XX:MaxPermSize=128m -jar craftbukkit.jar -o true
PAUSE

The drawback is that limkiting the PermSize does cause some performance impacts, however so far they are manageable and users don't really notice much difference.

Suggestion for developer:
Add in a section to the config where you can manually list plugins to ignore and/or include

The problem with RegionJukebox however is really the RegionJukebox Plugin is not handling the passed Events correctly I think.

Unfortunately for me that's the only plugin I need WGRegionEvents for! lol!

this is probably not an issue with this plugin, unless it is keeping stray references and has memory leaks accordingly. On the other hand, if you CAN isolate where the memory leak is, pointing it out, or contributing code would probably be much appreciated.

I do suspect that there is an issue with WGRegionEvents. I keep removing plugins and the error pops up for something new. All I had left were: Essentials, WorldGuard, Multiverse (suite) and still getting the same error passing events to Multiverse. I can try to dig for more information time permitting...

The only real area that I can see in the code that might be causing a memory leak, is https://github.com/mewin/WorldGuard-Region-Events/blob/master/com/mewin/WGRegionEvents/WGRegionEventsListener.java#L37

However, as the players are being removed from the map, on kick or disconnect, it should be fine.
Ideally however a weak hash map, or storing it using playernames may work better.

For the record, the error you are getting is simply an out of memory error and could be caused by anything at all, I've found that running spigot with netty vs the normal bukkit client can also make this error more readily triggered.

However I also run this plugin, and get the error as described so you may be on to something.

In addition, the flag you are adding to the command line, doesn't limit the permgen space, it is increasing it from the default.
