5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html :

pattern 6 (not sure)

6. Your problem:

sometime BREKEKE don't send ACK after receiving a 487 "Request Terminated"
so the problem is that multiple "487 Request Terminated"
messages are sent and the cpu reach 80%-100% due to java.exe
why?
