gincoind - high CPU usage

Im having an issue with gincoind (v. 1.1.0), both on linux as well as on macOS. On both platforms CPU usage is abnormal high, compared to other coin daemons. The described issue is happening with both the precompiled as well as self compiled version of the daemon.

I will post all details I got so far, if more information is needed, please let me know.

Komodo Notary Season 4

Dear Gincoin team ,

We are pleased to release the new Komodo 0.6.0 version, called "Draconic Serpent," which will hardfork the Komodo network to the 4th dPoW season on June 14th, 2020.
Exact height/timestamp can be found here ( approx. June 14th, 2020 03:00:00 PM UTC) : https://github.com/KomodoPlatform/komodo/blob/master/src/komodo_globals.h#L48

List of the third-party pubkeys for this season can be found here: https://github.com/KomodoPlatform/dPoW/blob/s4/iguana/3rd_party#L15

Please update your codebase accordingly for dPoW consensus protection and update infrastructure daemons/exchanges. We recommend contacting exchanges you listed on to pause all wallet-operations (withdraws & deposits) from June 13th, 12:00 PM UTC until June 15th 12:00 PM UTC in order to ensure a smooth network transition.

In case of questions don't hesitate to contact me by email alysakov at komodoplatform.com or in TG @ jl777fan

Have a great day and stay safe!
