Thanx. The old value was 1024. I've increased it to 65535.
But any way, would you like to explain me briefly why could that happened?
1) the server runs only for the application server (geronimo). no more
services. server runs without rebooting for a 2-3 weeks with permanent
workload (amount of user connections per day).
2) how the wicket development/deployment mode affects to the amount of
opened files.
