We have a strange problem. In our lab environment we are running a GlassFish v2ur2 instance. Two users access EJBs using ACC. Works well. After some hours the system is nearly standing still -- even if nobody worked anything in the meantime. If we try to open ACC, it just does nothing (not asking for password, nor showing our app's splash screen). The server just hangs. There are neither warnings nor errors in the server.log. Everything works fine, but just so slow that you think the server would be haning. After stopping and starting the instance, it works well again. The disk has 150MB free, RAM has 128MB free, CPU load is near one percent only.
The only exception found in the server.log is this one, and we think it is not the cause but just a result of shutting down the hanging ACC:
