Hi Daniel,<br>
<br><div class="Ih2E3d">
I checked the NW traffic, it's not very high, around 11k pkt/sec coming into SUT. With the similar amount of traffic, openser has not problem to deal with call setup/teardown, but not registration. Increasing udp buffer helps some, but not a lot.<br>
</div></blockquote>
<br>
then probably is whether syslog or db connection if you do authentication.<br>
<br>
If CSeq is not properly incremented by uac and openser/kamailio starts complaining a lot to a syncronous syslog, then it is very likely to be the cause. Later versions of kamailio should support negative values for debug, try to set it to -3.<br>
<br>
Also, what is the db_mode parameter value of usrloc?<br>
<br>

I am using 32 children. When things get wrong, with the error message I mentioned earlier, I can see messages generated by syslog can be very large. This may further degrade the performance and more packets get dropped.<br>
<br>
How much rate do you get for registration? Do you use authentication?<br>
<br>
I will try the test with larger hash size.<br>
<br>
Thanks,<br>

Hello,<br>
<br>
are you running kamailio/openser with higher debug mode (e.g.,<br>
debug set to a value higher than 3)?<br>
<br>
<br>
The debug mode I am using is 0, which is set in the .cfg file.<br>
<br>
ok, then is not high at all :-)<br>
<br>
<br>
<br>
<br>
Is your syslog configured asynchronous? I tested<br>
registration with<br>
very high rate and there was no performance issue. There is for<br>
sure something misconfigured.<br>
<br>
<br>
I am using solaris. The default mode is synchronous, and<br>
actually I don't think solaris support asynchronous write.<br>
openser use syslog to log in debugging information, right?<br>
<br>
<br>
by default yes. Do you get lot of log messages coming from openser<br>
in the syslog file?<br>
<br>
<br>
If the mode matters, can I just simply disable openser from<br>
logging in any information to files?<br>
<br>
<br>
There is compilation to disable all loggings, but it seems that<br>
the problem is somewhere else.<br>
<br>
What is the value of children in your configuration file? Also,<br>
try to increase the size of the hash table used by usrloc module:<br>
<a href="http://kamailio.org/docs/modules/1.4.x/usrloc.html#id2506464" target="_blank">http://kamailio.org/docs/modules/1.4.x/usrloc.html#id2506464</a><br>
<br>
Can you get stats from the network and see what was the reason for<br>
dropped packets? Full buffer?<br>
<br>
Cheers,<br>
Daniel<br>

Hi Henning/Daniel,<br>
<br>
Sorry to take such a long time replying back.<br>
<br>
For my rig, I am using the memory as location back-up. When<br>
the issue occurs, I see many registration request sent from<br>
SIPp but not many 200 replies. netstat shows a huge<br>
amount of<br>
packets get dropped.<br>
<br>
Also I realized the issue only occurs when SIPp tried to<br>
register many users in a very short time. With the same<br>
number<br>
of users, the issue goes away if registration rate is kept<br>
lower. When the issue occurs, usrloc module contends lock a<br>
lot calling from new_ucontact(), and many system time<br>
is spent<br>
in yield system calls. So it looks more like a performance<br>
issue to me.<br>
<br>
Thanks,<br>

Hi joy,<br>
<br>
no, there is no such a limitiation, we've more<br>
registered<br>
users.<br>
The invalid<br>
CSEQ error you see is not related to this<br>
observation. The<br>
error<br>
means that a<br>
device tried to do re-registration (same callid), but<br>
without properly<br>
increasing the Cseq number in the REGISTER request -<br>
RFC3261 says that<br>
requests from the same dialog (like REGISTER +<br>
re-REGISTER)<br>
must have<br>
increasing cseq.<br>
<br>
What db_mode do you use in your usrloc? Do you see<br>
any other<br>
errors in the<br>
logs?<br>
<br>
Cheers,<br>
<br>
<br>
Henning<br>
