[Devel] Update about "OpenSER crashed with 10 calls/sec load test"

[Di-Shi Sun]

Hi,

According to Daniel's suggestion, we download OpenSER from CVS. There are two problems:

1. OpenSER does not parse VIA field from SIP INVITE message. The INVITE message is like this:

INVITE sip:9#1234567890 at 216.162.34.110:5060 SIP/2.0
Via: SIP/2.0/UDP 216.162.34.104:46487;branch=z9hG4bK-1-0
From: 0987654321 <sip:0987654321 at 216.162.34.104:46487>;tag=1
To: sut <sip:9#1234567890 at 216.162.34.110:5060>
Call-ID: 1-10627 at 216.162.34.104
CSeq: 1 INVITE
Contact: sip:0987654321 at 216.162.34.104:46487
Max-Forwards: 70
Subject: Performance Test
Content-Type: application/sdp
Content-Length:  140

v=0
o=user1 53655765 2353687637 IN IP4 216.162.34.104
s=-
c=IN IP4 216.162.34.104
t=0 0
m=audio 10000 RTP/AVP 0
a=rtpmap:0 PCMU/8000

2. After we hard code the source IP address, some calls complete, but some do not. It logs:

Oct 20 14:04:03 fedora5 /usr/local/sbin/openser[9636]: ERROR: append_branch: too long uri: 
Oct 20 14:04:03 fedora5 /usr/local/sbin/openser[9636]: ERROR:tm:t_forward_nonack: no branch for forwarding 
Oct 20 14:04:03 fedora5 /usr/local/sbin/openser[9636]: ERROR: w_t_relay_to: t_relay_to failed 
Oct 20 14:04:03 fedora5 /usr/local/sbin/openser[9636]: ERROR: run_failure_handlers: Error in do_action 

These error logs are generated for the SIP INVITE messages just like above.

Thanks,

Di-Shi Sun.
