Spigot complains if you launch with the default MaxPermSize.
The developers there could make better suggestions as to why thats the case.
Spigot warning:
```
Warning, your max perm gen size is not set or less than 128mb. It is recommended you restart Java with the following argument: -XX:MaxPermSize=128M
Please see http://www.spigotmc.org/wiki/changing-permgen-size/ for more details and more in-depth instructions.
