Recently, ethereum mainnet miners started accepting 10mm gas limit. I think kovan testnet should also set 10mm gas limit.
If you agree, please go to your node, and change in
gas_floor_target = "10000000"
Or maybe wait for POA team to release new update on github’s playbook.
I think it will be easier to just ssh into the node and set the settings.
Don’t forget to
sudo systemctl stop poa-parity
