Hi Rahul,<br>
<br>
What presence event is there ? Maybe the Notifies (first and second)
are the result of the same event and triggered from the same process
(this explaining the serial processing of them).<br>
<br>
What OpenSIPS version are you using ? as normally, for sequential
presence requests, the opening of new TCP conns is forbidden.<br>
<br>
Regards,<br>
