<p class="MsoNormal"><span style="color:blue">One more

you have provided your fix.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">Am using REST API
as, async. After receiving the response for the HTTP
request, I will process the incoming SIP INVITE.

<p class="MsoNormal"><span style="color:blue">If am sending 50

perfectly fine.

<p class="MsoNormal"><span style="color:blue">If am sending 50
calls at 5 calls per sec from sipp, most of the call fails.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:blue">If I look at logs
I could able to see that for failure case, it hits
start_async_http_req, but never resume function is called.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">It is printing </span><span
style="color:red">LM_DBG("done, no need for async!\n"); and
returns ASYNC_SYNC;</span><span style="color:blue"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">Any idea why for
few calls, it is not acting as async? Particularly if I
increase cps, am seeing this behavior.

“Connection_timeout” value as ‘1’ and ran 2 sipp calls.
