[OpenSIPStack] FW: FW: Memory Leak in Proxy and Full Mode

Hi Joegen
I found something really weird. If I change the order of headers in SIPMessage::Cleanup() the memory leak varies.
For example, if I clean m_AllowList and m_ViaList first of all the memory leak decrease:
void SIPMessage::Cleanup(){ GlobalLock();
if( m_AllowList != NULL ){ delete m_AllowList; m_AllowList = NULL; } /// special headers if( m_ViaList != NULL ){ delete m_ViaList; m_ViaList = NULL; }
.....
I will continue searching. ¿Is there a way to configure PMEMORY_CHECK for release?
Thanks for your help.

Hi Joegen I think this is a memory leak because after all messages are sent the memory never go down.The code added in B2BUserAgent::Registrar::ProcessUpperRegKeepAlive() waits 5 seconds and sends the first Invite, then waits 5 seconds , sends the second Invite, waits 5 seconds more and finally sends 4998 Invites with a 40 ms delay between each one. void B2BUserAgent::Registrar::ProcessUpperRegKeepAlive(){ DWORD delay = 5000; DWORD numberOfPackets = 0; while( !m_UpperRegSync.Wait( delay ) ) { if(numberOfPackets < 5000) { OString testRequest = "INVITE sip:5435155555@192.168.0.5:5060 SIP/2.0\r\nContact: <sip:4284623@192.168.0.10:5060>\r\nCSeq: 101 INVITE\r\nFrom: <sip:4284623@192.168.0.10>;tag=5A3745C-2418\r\nTo: <sip:55555555@192.168.0.206>\r\nVia: SIP/2.0/UDP 192.168.0.206:5060;branch=z9hG4bK63028de3a6b7743a\r\nVia: SIP/2.0/UDP 192.168.0.10:5060\r\nRecord-Route: <sip:192.168.0.206:5060;lr>\r\nAllow: INVITE, OPTIONS, BYE, CANCEL, ACK, PRACK, COMET, REFER, SUBSCRIBE, NOTIFY, INFO\r\nUser-Agent: Cisco-SIPGateway/IOS-12.x\r\nCall-Id: " + OString(numberOfPackets) + "@192.168.0.10\r\nMax-Forwards: 6\r\nExpires: 180\r\nContent-Length: 235\r\ndate: Thu, 22 May 2008 21:52:32 GMT\r\nsupported: timer\r\nmin-se: 1800\r\ncisco-guid: 926237238-662704605-3106705574-3236916195\r\nremote-party-id: <sip:4284623@192.168.0.10>;party=calling;screen=no;privacy=off\r\ntimestamp: 1211493152\r\nallow-events: telephone-event\r\ncontent-type: application/sdp\r\n\r\nv=0\r\no=CiscoSystemsSIP-GW-UserAgent 7402 717 IN IP4 192.168.0.10\r\ns=SIP Call\r\nc=IN IP4 192.168.0.10\r\nt=0 0\r\nm=audio 19298 RTP/AVP 0 19\r\nc=IN IP4 192.168.0.10\r\na=rtpmap:0 PCMU/8000\r\na=rtpmap:19 CN/8000\r\na=ptime:20"; testRequest = ParserTools::LineFeedSanityCheck( testRequest ); SIPMessage * msg = new SIPMessage( testRequest ); OString addrStr = "192.168.0.147"; OString portStr = "10000"; SIPHeader rcvAddr( "RCVADDR", addrStr ); SIPHeader rcvPort( "RCVPORT", portStr ); SIPHeader rcvTran( "RCVTRAN", "udp" ); msg->AddInternalHeader( rcvAddr ); msg->AddInternalHeader( rcvPort ); msg->AddInternalHeader( rcvTran ); msg->SetInterfaceAddress( "192.168.0.202" ); msg->SetInterfacePort( 5070 ); OStringStream traceStream; traceStream << "<<< " << msg->GetStartLine() << " " << " SRC: " << addrStr << ":" << portStr << ":UDP" << " enc=" << msg->IsEncrypted() << " bytes=1103"; OStringStream strPacket; strPacket << *msg; COMPOUND_LOG_CONTEXT( LogInfo(), msg->GetCallId(), traceStream.str(), LogDebugHigh(), strPacket ); SIPTransport::NotifyRead( traceStream.str() ); if( msg->IsInvite() ) { SIPMessage * trying = new SIPMessage(); msg->CreateResponse( *trying, SIPMessage::Code100_Trying ); Via via; msg->GetViaAt(0, via ); if( via.IsBehindNAT() ) { SIPURI srcURI; srcURI.SetHost(addrStr); srcURI.SetPort(portStr); trying->SetSendAddress(srcURI); } if( msg->IsEncrypted() ) trying->SetEncryption( TRUE ); GetTransportManager()->ProcessOutbound( trying ); } GetTransportManager()->OnTransportEvent( new SIPTransportEvent( msg, SIPTransportEvent::UDPPacketArrival ) ); if (numberOfPackets > 1) delay = 40; numberOfPackets++; } }} The SIP timers B and H are set to 20 ms. #define SIP_TIMER_B 20 #define SIP_TIMER_H 20 After all messages are sent, I wait for a long time but the memory used doesn't decrease.

Case 5 5 sec -> 1 Invite -> 5 sec -> 1 Invite -> 5 sec -> 4998 Invite (80 ms) -> 5 min1)Mem Usage 8344k 8932k 8952k 9332k2)Mem Usage 8376k 8968k 8992k 9276k The only type of error in the log is : 102:42:36.691 ERR: [CID=0x0000] UDP Socket Read Error (Socket not connected) in case 1 appears 5219 times. I don't know if this error is linked with the leak. The log is attached. This behavior doesn't seem to be because of transactions waiting for timers. Maybe is because some type of conflict with shared resources or mutexs, but I really don't know. Any idea? If you need more info, please let me know. One more thing, I suggest to increase MAX_SIP_MESSAGE_LENGTH because i had problems with Invites with a lot of headers (record-routes, vias, etc) and long bodies. #define MAX_SIP_MESSAGE_LENGTH 2048 ----> #define MAX_SIP_MESSAGE_LENGTH 4000 Thanks for your help.
