<p class="MsoNormal"><span style="color:blue">One more observance. Am trying to load test on the main branch where you have provided your fix.

<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 calls at 2 calls per sec from sipp, -in this case it works perfectly fine.

<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.

<p class="MsoNormal"><span style="color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:blue">I have configured “Connection_timeout” value as ‘1’ and ran 2 sipp calls.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">After TCP port is opened, HTTP request is sent out approx. 95 to 100ms later. Am attaching the log of the opensips by enabling debugging log.

<p class="MsoNormal"><span style="color:blue">I took the code from master branch and tested it out. If you find everything OK let me know.

<p class="MsoNormal"><span style="color:blue">Or if you feel to test any specific scenario please update me, so that I can test and share you the results.

<p class="MsoNormal"><span style="color:blue">P.S:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">One more observance.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">In the case of synchronous, TCP port is opened within 8 ms, whereas in the case of async TCP port is opening after 100 ms.
