Hi Igor, thanks for your fast answer (as usual)!!!
So this also means that it's the high load on the bigger applications which is causing that *only* the smallest (and less used) Wicket app has at the moment the problem. Do you agree? We will try to monitor the usage by all the application deployed. I don't know if Jboss has already something with this value available (ideally an Mbean). Ciao, V.
