Hi all, thanks for all the input. We could sort out the Jitter/MOS problem as a temporary Network problem with one of our carriers. about the CPU: how should i make sure that it is really eating 100% CPU? "ps aux" shows the freeswitch process at arround 30% so it seems to not really consume 100%cpu as htop still tells me. USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND freeswi+ 30074 30.6 3.9 8582604 636456 ?

if it really consumes 100% CPU with few calls then it's abnormal. kill it with SIGABRT (make sure it will dump core before that), get a backtrace with gdb and open a github issue. before doing this you need to make sure it's really eating 100 % CPU, this screenshot is not very relevant. Also, you need to make sure you don't have real packet loss. Perhaps it's a matter of dimensioning, eg: how many simultaneous calls do you expect to have on that hardware, what codec, etc.

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

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
