Server crash on player logout

Hi,

I had to zip the log as it was too big to be viewed on gist via browser.

Error in question starts at line 96396:

It's a private modpack. This crash only happens when certain players logout, and it happens with both Java 7 and java 8.

The client freezes and then disconnects, and the error is received on both client and server, then server crashes. Unable to reliably reproduce. The server and client are both always within their memory restrictions.

 

If all you can do is rule out forge as the culprit, that's fine too.

 

Thanks

Intersting you have a mod installed that is trying to parse screwed up json. Sadly the stack trace cuts out so I cant tell you which mod, just that one of them is.

Thanks for the reply.

 

Crash report if it helps at all, but I'm aware it may not.

In the meantime I'll get trialanderror-ing.

Think I found it, but I'm not a JSON expert..

A ForgeEssentials player file.

Is incorrect syntax what you meant by screwed up?
