[OpenSIPS-Users] dialog bye_on_timeout and other issues

[Alex Massover]

Hi,

I have a strange behavior of OpenSIPS 1.6.2. First dialog module _sometimes_ sends a wrong bye (generated by dialog module on timeout):

Here's a correct one:

BYE sip:972123456789 at 212.179.159.9:7640;transport=UDP SIP/2.0
Via: SIP/2.0/UDP 212.179.159.18;branch=z9hG4bKd6c7.7f7a3d36.0
To: <sip:+496925420990 at 212.179.159.18:5060>;tag=8548
From: <sip:+972542384166 at 212.179.159.9:5061>;tag=8547
CSeq: 2 BYE
Call-ID: 8547-15512 at 212.179.159.9
Content-Length: 0
Max-Forwards: 70

And here's a wrong one:

BYE sip:212.179.159.9:7640 SIP/2.0
Via: SIP/2.0/UDP 212.179.159.18;branch=z9hG4bKc6c7.7ecb1057.0
To: <sip:+496925420989 at 212.179.159.18:5060>;tag=8547
From: <sip:+972542384166 at 212.179.159.9:5061>;tag=8546
CSeq: 2 BYE
Call-ID: 8546-15512 at 212.179.159.9
Route: <sip:972123456789 at 212.179.159.9:7640;transport=UDP>
Content-Length: 0
Max-Forwards

In a wrong one there's Route header inserted (by mistake?) and the message is cut at Max-Forwards line. It's missing ":70\r\n".

Both of the BYEs above I got just by running test with SIPP. This can happen even with single call, not related to stress. I.e. one call it might send a correct BYE and another call a corrupted BYE, without any reason, because calls are exactly the same.



Another issue is, looks like t_newtran() is unable to handle retransmissions. In this test UAC and UAS are in the same machine (.9), and you can't see  INVITE from OpenSIPS (.18) to UAS because it's fragmented.

This issue happens during stress test.

Any ideas, please? The OpenSIPS 1.6.2 is compiled with system malloc and runs over VMware.
