Unusually high RAM usage(can't find the cause)

At first I thought this was due to the server provider, but I have moved accross 3 different providers all having the same issue.

What happens is the server starts up as normal, and then while it stays online, the ram usage slowly creeps up and up and up, no matter how many players are online. Right now for instance there are 2 players online and my server is using up 1.5GB of ram - to me it sounds like a memory leak.

No errors at all, all plugins are loading fine at startup and are all up to date. And as far as I can tell I'm the only person having this issue.

Build: latest dev beta build(2060)

Plugins:
BOSEconomy
bpermissions
LaunchME
LWC
nChat
Showcase Standalone
Simplespawn
Worldborder
Worldedit
Worldguard

Again not that many plugins and I've checked them all out, none are reporting any memory leaks or anything with them. I would appreciate any help.

 

The way to find out what is causing this is to start with a server with no plugins. then add your plugins one by one while waiting between them to see if your ram usage spikes. I know that cb build 2060 does not have a memory leak, I also know that world border 1.5.3, world edit5.3 build 1108 and worldguard 5.5.2 build 589 do not have memory issues as well cause I am running them on my server and have no issues, the remainder of your plugins i do not know about.
