Silent delay upon restart with prior db state of 24hours worth of pubnet

[sreuland]

What version are you using?

20.3.5

What did you do?

Ran rpc for several days configured for pubnet, the on-disk db had maximum window of data allowed.
Stopped the rpc service.
Started the rpc service.

What did you expect to see?

new logs emitted and http service is listening right after the rpc service is started.

What did you see instead?

the rpc process is running on the o/s, but no logs emitted and no http service is bound/listening on tcp port, this state lasted for about 30minutes.

I think this condition will be resolved/obsoleted by #115 which removes in-memory data storage in favor of all data on disk, @2opremio do you agree, since the delay observed here is caused by a blocking routine that copies db to memory first before it starts http service?

[2opremio]

Yes, I agree!

Closing in lieu of #115
