[Freeswitch-users] XML_CURL max connection limit

[Michael Jerris]

This is adding a feature to allow timeout to be set in ms instead of seconds.  This is not a problem, its a feature, that was added a while ago.  Until you can determine if the request is being sent for the one thats failing, your not going to solve this issue.

In SIPp, there are new calls created and old ones hang up at every instant, so i see HTTP Error 0 when calls climb over 1638 and then immediately when some calls hang up everything starts working normal again, then SIPp generates more call and again i get this error. Its pretty difficult to identify if failed hit is in the trace or not. I will debug more tomorrow.

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.
