I am developing VoIP client for S60 3rd Edition FP1 devices. I found a strange problem of application crash with ESock_client panic 14. Application open RSocketSrv, open & start RConnection, initialize SIP stack and then send SIP Register. When transport failure callback is received, application shutdown SIP Stack and then restart RSocketSrv & RConnection. Sometimes before the completions of callback application crashes with ESock_client error 14. Here application just opens RSocketSrv & RConnection but does not send or receive data. What can be the reason in this scenario for ESock panic???
