Is the request going to your server and getting no response?

<div dir="ltr">Hi,
<div><br>
</div>
<div>Is there any connection limit perhaps hard coded
anywhere in xml_curl module? I am load testing FS with
xml_curl to provide config, directory and dial-plan. I
observed i start getting HTTP ERROR 0 when i have around
1600 concurrent calls on machine with media. Although i
see no sign of system overload either on FS (load
average < 1.8) or Apache (load average < 4,75).
Both have plenty of RAM and bandwidth free.</div>
<div><br>
</div>
<div>Is there anyway to get rid of this HTTP ERROR 0? It
must be generated by FS internally, since i don't see
anything like this error in Apache logs.</div>
<div><br>
</div>
<div>Below 1,638 concurrent calls @ 50 CPS, i get success
rate of 99.999% but as soon as it crosses this mark,
success rate drastically drops to 60% and even below
(when concurrent calls go beyond 2,000). Here is error
console log.<br clear="all">

I think you need to do something with Apache configuration. Maybe
increase apache child instance/Threads will give you better
performance. <br>
