Subject Strange "session"s causing memory-leak
Date Thu, 21 Feb 2013 18:25:28 GMT
Hello list

I'm having a bit of trouble with my wave instance. Up until recently
it worked just fine. But for ~24h it has now been eating up a lot of
memory. It just keeps consuming more and more until it eventually
runs out of memory. After a restart it does just fine. Before that
it only consumed a fraction of the memory it does now.
Looking at the log files there are a lot of reoccuring exceptions
that look like this:
(Here are the most important lines):

INFO: New websocket connection set up for user null
Feb 21, 2013 6:19:26 PM com.glines.socketio.server.DefaultSession
WARNING: Session[qQne3U2q7GlnmE5m_dnT]: Exception thrown by
java.lang.IllegalArgumentException: Auth token invalid

Is this some kind of attack against the server?
