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">
