We need running with dialogs because we have to act as a B2BUA and we have put gov.nist.javax.sip.REENTRANT_LISTENER = true. It's very strange the stack is not able to process more requests if the CPU usage is not very high. I don't know if perhaps it can be a problem of synchronization or something so.
