[Serusers] FIN,ACK right after a successful registration

Hi Serusers, I am suffering from a weird problem in SER. Maybe you would help me with that. I have SER 0.8.11(TCP Support) on Linux Redhat v9. I am running our SIP user agent emulator against SER in my configuration. SER proxy is sending "FIN, ACK" to the user agent right after the REGISTER (200 OK). Although there is one established TCP connection and a successful registration, SER is terminating the TCP connection. Any help would appreciate Many thanks in advance Ahmet _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus
