We are running our testnet with POA, but every so often the network stalls with:
WARN miner Closing the block failed with error Engine(FailedSystemCall("pleas e ensure the contract and method you\'re calling exist! failed to decode empty bytes. if you\'re using jsonrpc this is likely due to jsonrpc returning `0x` in case contract or method don\'t exist")). This is likely an error in cha in specificiations or on-chain consensus smart contracts.
This was fixed in POA, can someone reference me to the fix?
