Issue being fixed or feature implemented
Cache population for old quorums is a cpu heavy operation and should be avoided for inactive quorums at least oin
ScanQuorums. This issue is critical for testnet and other small network because every mn participate in almost every platform quorum and cache population for 2 months of quorums can easily block everything for 15+ minutes on a 4 cpu node. On mainnet quorum distribution is much better but it's still a small waste of cpu (or not so small for unlucky nodes).#5761 follow-up
What was done?
Do not start cache population for outdated quorums, improve logs in
StartCachePopulatorThreadto make it easier to see what's going on.How Has This Been Tested?
run a mn on testnet
