[reSIProcate] Leaking transactions

[kaiduan xie]

Yes, this is a bug in resiprocate, and a bug in rfc 3261. Same thing happens for UAS INVITE transaction.

Hi 
there,

 

I am getting 
a memory leak in my application when I end my UAC session 
while the session is in a 'UAC_Early' state 

i.e. I've got a '180 
Ringing' from the remote UAS endpoint but I haven't received a '200 OK' as 
yet.

 

I'm getting the 
following statistics message from the stack afterwards:

 

TU summary: 0 
TRANSPORT 0 TRANSACTION 0 CLIENTTX 1 SERVERTX 0 TIMERS 
0
Transaction summary: reqi 0 reqo 6 rspi 8 rspo 0
Details: INVi 0/S0/F0 
INVo 2/S0/F1 ACKi 0 ACKo 1 BYEi 0/S0/F0 BYEo 1/S1/F0 CANi 0/S0/F0 CANo 0/S0/F0 
MSGi 0/S0/F0 MSGo 0/S0/F0 OPTi 0/S0/F0 OPTo 0/S0/F0 REGi 0/S0/F0 REGo 2/S1/F1 
PUBi 0/S0/F0 PUBo 0/S0/F0 SUBi 0/S0/F0 SUBo 0/S0/F0 NOTi 0/S0/F0 NOTo 
0/S0/F0
Retransmissions: INVx 0 BYEx 0 CANx 0 MSGx 0 OPTx 0 REGx 0 finx 0 
nonx 0 PUBx 0 SUBx 0 NOTx 0


The 
'CLIENTTX 1' in the TU summary doesn't go away no matter 
how long I wait - I assume this means a transaction has leaked 
somehow?

I am ending the 
session by calling ClientInviteSession::end() and 
subsequently calling process() on the stack and DUM - is there some step I 
am missing here?

 

I'm using 
reSiprocate 1.1 built on VC8 SP1 and my SIP proxy is 
asterisk.

 

Any help would be 
appreciated
