[Freeswitch-users] XML_CURL max connection limit

[Muhammad Shahzad]

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.
