I have already set MaxClients to 2048, but that limit is never reached. Thank you. On Wed, Jun 5, 2013 at 4:17 PM, Samir Doshi <smrdoshi@gmail.com> wrote:

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

Hi,
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.
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.
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.

Although this setup is more then sufficient for my requirement but i just want to know if i can extend it beyond, since i still have lot of resources free.
OS: Debian 6.0.7 x64 Apache: 2.2.16 FreeSWITCH: 1.5.1b+git~20130424T005233Z~66d1755b06
Both FS and Apache are running on separate dedicated machines on same LAN.
Thank you.

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