Can't load if I use more than 12 plugins.

[JoeCow]

I really like the idea of this plugin but if I try to load more than 12 plugins realms will not load. I tried with a bunch of different plugin combinations thinking there was some kind of plugin conflict but the only thing I could do to get it to work was use 12 or less plugins. Anytime I would use 13 it would no longer work. Let me know if you need any other details.

Hello, good morning,
Caused by: java.lang.NoClassDefFoundError: net/aufdemrand/sentry/SentryTrait
You need the sentry plugin to install. When you have installed citizens.
When not installed citizens, then please reply, then its an error .

I had sentry and citizens installed when I was testing that. It would work fine when I had 12 plugins or less but as soon as I would hit 13 or more it would no longer find sentry.

[Krglok]

Ok, i make a test and look at the source of issue Position
In my Server Installation are 20 plugins, so it cannot be the number of plugins.

[Krglok]

The plugin.yml has no depends: Sentry
I think this is the error cause

[Krglok]

Hello agian,
Can you give me a list of your plugins you installed on your server.
I cannot reproduce the error . So I cannot verify the a fixe.
Thank you,

Krglok

I did a clean install and it still happens on both my debian server and my local windows machine as soon as I get over 12 plugins regardless of what plugins I use. Maybe I am doing something wrong. Should I be using the latest dev build of sentry and citizens or the latest version on bukkit?

[Krglok]

hmm.. what machine yo have ? I think you need 3-4 GB RAM for the server. depends on your world and the plugins. Have you set the ram parameter for startup ?
This my old debian start :
java -d64 -Xms1500M -Xmx4500M -jar craftbukkit.jar

has mulitple worlds and a large world of 20000x20000 blocks
upto 32 plugins

when you start the server on windows you should use BukkitGUI.exe. This is a bukkit project and you can download it from bukkitdev

[JoeCow]

Hmmm tried -xmx10000M and still no good. I'll just put it on it's own server for now with bungee.
