[Freeswitch-users] FreeSWITCH changing max_sessions automatically

[Ken Rice]

You¹re hitting a melt down protection... Once it reaches a limit and cant
allocate the additional resources for creating anew session it will back
down the max sessions limit to help save itself...

The PEAK SPS there was a value seen at some point the SPS buffer...
Depending on you beating the machine to death it is possible that number got
skewed due to a timer miss
