Asterisk 16.2.0 + pjsip 2.8 abnormal CPU Load and taskprocessors errors

Asterisk Asterisk Support

Hello, I have asterisk 16+freePBX on Hyper-v (28 cores E5-2670 2.60GHz + 16Gb ram)
And performance of this system is extremely low. The server shows up to 50% CPU usage with only 30 calls.
Other similar installations(asterisk 13) on similar hardware gives up to 200 calls easy.

And there many errors like this:

[2019-03-27 13:36:18] WARNING[56721][C-00005810] taskprocessor.c: The 'subm:manager_topic-00000007' task processor queue reached 3000 scheduled tasks again.

How to know, where is the problem?
Thanks
