Defined GasLimit in genesis file and in web3j gasprovider

Question

Im having issues when I try to implement a back end that generate smart-contract transaction calls using web3j. But I'm a lit confused with the gas limit concept. I have defined inside the genesis file a gas limit value of:

"gasLimit": "0xE0000000" --> 3758096384

And inside the web3j gasProvider a value of:

30_000_000L

At the time of making the transactions there comes a time which I cannot perform operations. And I get the following exception:

java.lang.RuntimeException: java.lang.RuntimeException: Error processing transaction request: exceeds block gas limit
    at org.web3j.tx.Contract.deploy(Contract.java:391)
    at org.web3j.tx.Contract.lambda$deployRemoteCall$10(Contract.java:496)
    at org.web3j.protocol.core.RemoteCall.send(RemoteCall.java:30)

This exception appear when I deploy new SC and also when I do SC function calls. In one way or another, I cannot perform any type of operation and I have to restart the blockchain.

• The generated exception who gives me? The blockchain or web3j for having defined a value in the GasProvider lower than that of the genesis?

• But the gas limit defined in the genesis is not supposed to be only for the first block?

• Why I cant make transactions and how can I manage this situation in a production environment and recover the data and the great functionallity?

• How can I know a great gasLimit value for production?

UPDATE

QUORUM_CONSENSUS: default to istanbul

QUORUM_DOCKER_IMAGE: default to quorumengineering/quorum:2.2.3

QUORUM_TX_MANAGER_DOCKER_IMAGE: default to quorumengineering/tessera:0.9

Answer 1

So, my recommendation is to update to the latest version: v2.3.0. Depending how the 2.2.3 was configured, minting node may ignore globally set block size, to ensure that it doesnt, use --miner.gastarget XXX and --miner.gaslimit XXX-- set these sufficiently high for your use case.
