<br>
we are currently experiencing jitter and dropping MOS score on an <br>
increasing amount of calls on our system.<br>
<br>
i can't see any increased load on our system (neither CPU nor I/O wise).<br>
<br>
Current stats:<br>
<br>
~ 15Mbit/s network traffic (on a 1Gbit/s network)<br>
load average: 1,10, 0,82, 0,91 (16 core machine)<br>
memory used: 2,26GB/16GB<br>

FreeSWITCH (Version 1.10.1 -release-12-f9990221e6 64bit) is ready<br>
137634 session(s) since startup<br>
218 session(s) - peak 245, last 5min 222<br>

1000 session(s) max<br>
min idle cpu 0.00/95.37<br>
Current Stack Size/Max 244K/244K<br>
<br>
System ist not virtualized.<br>
<br>
the only "strange" thing i see is the freeswitch "main"process that <br>
consumes (according to htop) >=100% cpu (see attached screenshot).<br>
Can this be the problem? if yes what can i do against it.<br>
<br>
if not what are possible bottlenecks i should weed out?<br>
<br>
if you need any additional informations to help me sort out this problem <br>
please don't hesitate to ask.<br>
<br>
Thanks in advance and best regards<br>
Christoph<br>
