[Freeswitch-users] FreeSWITCH changing max_sessions automatically

[Muhammad Naseer Bhatti]

No i am definitely not going to that SPS limit. The peak was set to 400 so maybe this is just a skewed value. 1000 session does not look to be high load. The call is bridged and set to play silence and disconnects at random time under 1 minute.  The resources on the server also clearly seem to be available. I am not gearing this towards a how do i .... Performance kind of a thread but could there be something unusual here?

This happens when typically I bridge around 1000 sessions and whatever value I set to sps and max_sessions, it comes down.
