[Freeswitch-users] Jitter and dropping MOS score

[Christoph Russow]

Hi all,

we are currently experiencing jitter and dropping MOS score on an 
increasing amount of calls on our system.

i can't see any increased load on our system (neither CPU nor I/O wise).

Current stats:

~ 15Mbit/s network traffic (on a 1Gbit/s network)
load average: 1,10, 0,82, 0,91 (16 core machine)
memory used: 2,26GB/16GB

freeswitch at lc1> status
UP 0 years, 12 days, 13 hours, 30 minutes, 24 seconds, 649 milliseconds, 
831 microseconds
FreeSWITCH (Version 1.10.1 -release-12-f9990221e6 64bit) is ready
137634 session(s) since startup
218 session(s) - peak 245, last 5min 222
1 session(s) per Sec out of max 30, peak 8, last 5min 2
1000 session(s) max
min idle cpu 0.00/95.37
Current Stack Size/Max 244K/244K

System ist not virtualized.

the only "strange" thing i see is the freeswitch "main"process that 
consumes (according to htop) >=100% cpu (see attached screenshot).
Can this be the problem? if yes what can i do against it.

if not what are possible bottlenecks i should weed out?

if you need any additional informations to help me sort out this problem 
please don't hesitate to ask.

Thanks in advance and best regards
Christoph
