`2021.12.12 04:24:12.020896 [ 491 ] {} <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

Why `reserved logs -1530494976` (negative number)?
`timeout 0 - 0` - not obvious what does it mean.
`snapshot receiver INCLUDED` - it is screaming for what?
