-------------------------------------

yesterday our this server's asterisk is not working after "core restart now"
we had implement new server almost equal configuration

Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                20
On-line CPU(s) list:   0-19
Thread(s) per core:    2
Core(s) per socket:    10
Socket(s):             1
NUMA node(s):          1
Vendor ID:             GenuineIntel
CPU family:            6
Model:                 85
Model name:            Intel(R) Xeon(R) Silver 4210 CPU @ 2.20GHz

RAM Size 16 GB

our call flow is like 

server 1 originate call via ami and pass some call related information.

server 2 - where asterisk installed and telecom connected 
accept the originate command and dial customer number.
after the answer the call.. play a audio from URL which location we receive  via ami in form of variable.
after this. we record user side response and send it to google via api and receive text from google. based on text received play the next audio.
after call hangup send all info to ami server via php api.

today at starting on calls, server load was 2 or 3 but as time goes now load reach around 22 where our cpu cores are 20..
on this condition most of calls have voice related issue.

> ami originate call from another server --- asterisk dial number--- play audio file--- google API audio to text---- and play another audio based on response.
