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

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