First thing to look at is check your lua scripts if you have any. It is very strange for fs to take 100% of cpu on such low loads. So check your call flows. On Wed, 6 Oct 2021 at 00:58, Christoph Russow <russow@emtex.de> wrote:
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
