Expected behaviour

Should producing new blocks after finish head state missing reparing

Actual behaviour

• all nodes stop producing new blocks and stuck with continuous message "Looking for peers peercount=8 tried=0 static=0"
• the geth nodes can't be normally stopped
• if kill the geth nodes hardly, and then restart them, the problem repeats

Steps to reproduce the behaviour

1. start seven privnet by runnning command
   make privnet_start_seven
2. try to stop privnet and make head state missing (for example, shutdown vm hardly)
3. start privnet again and wait for the repairing process
4. after all nodes finish repairing, it won't generating new blocks
5. the geth processes can't even be stopped by runing the below command, and producing logs "Looking for peers peercount=0 tried=0 static=0"
   make privnet_stop

About “missing state head”, ref ethereum/go-ethereum#30867 (comment).

It seems like idled while synchronization, the repairing target is 6792, but the local block height is 6153.

I think we didn't change Geth in this part. Anyway, just avoid killing Geth forcefully.

I think we didn't change Geth in this part.

In this part - no. But we also need to ensure that this particular problem is not caused by yet another refactoring of the code that awaits sealing proposal on the dBFT side (#402). From the node's logs I see that engine wasn't even started, but still we'd better be sure.
