Ah sorry, I had assumed this was already confirmed - good catch Michael.

As said above, if you have not confirmed this already, then you will need to do so before moving on.

Did you get to confirm if the request was really going to the server or not?  If it is not, then all of the other suggestions above are completely invalid.

The request does not comes to web server, at least this is what i see in web server logs. I will run a trace and see if it actually is sent out to web server or not.

Thank you.

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.
