Hey Operators!
Recently I am seeing following log record in my producer cardano-node:
[p1:cardano.node.Forge:Error:35] [2020-09-15 17:05:52.00 UTC] Updating the forge state in slot 8623261 failed because: OptSkip (OptCons (WrapForgeStateUpdateError {unwrapForgeStateUpdateError = KESKeyAlreadyPoisoned (KESInfo {kesStartPeriod = KESPeriod 4, kesEndPeriod = KESPeriod 66, kesEvolution = 0}) (KESPeriod 66)}) OptNil)
Is it something I need to take action?
How does the “KES poisoning” process work and what does it do?
Thank you!
Marek
