Hi there!

We are using glassfish v2b58 as a server for our service (ejb's + google web toolkit). It great combination - works ok but... we discovered after some period of time our server makes 100% load on one core of our cpu server. After some investigation we received this message:

and it is repeating constantly (it's logged only when we set logging finest for web module).

I know - it's not easy to say what is wrong... but maybe you could give us any suggestion where to start?
