As far as I remember I've decreased it to 10k because of slow start in stress tests with thread fuzzer.

Stress tests looks ok now, except:
Stress test (thread, actions) - <Fatal> Application: Child process was terminated by signal 11. - segfault without stacktrace
Server logs contain messages with reserved logs -1530494976:

2021.11.16 20:46:13.107636 [ 540 ] {} <Information> RaftInstance: parameters: timeout 0 - 0, heartbeat 0, leadership expiry 0, max batch 100, backoff 50, snapshot distance 10000, log sync stop gap 99999, reserved logs -1530494976, client timeout 10000, auto forwarding ON, API call type ASYNC, custom commit quorum size 0, custom election quorum size 0, snapshot receiver INCLUDED, leadership transfer wait time 0, grace period of lagging state machine 0, snapshot IO: BLOCKING

Most likely incorrect print in NuRaft again...
