After submit block, AION node has no result.

yrjphf commented 4 years ago

Description

When my pool submit a solution, node should print the log: block submitted via api OR Unable to submit block via api.

But it is often the case that the node does not follow.

So, the block I dug out became a orphan block.

Why does this happen? Can this problem be solved?

System Information

I'm running:

Which Aion version?: oan node 1.5.3
Which operating system?: Linux
Which distributor and version?: Ubuntu 18.04
How installed?: from release node
Are you fully synchronized?: yes
Did you try to restart the node?: yes

So for your case in the kernel basically only 2 scenarios could happen.

The kernel chain database just re-branching (follow the network highest chain). We can fix this issue in the next release (By returning the meaningful log)

The kernel will cache the last 64 mining block templates (we use LRU map to drop the aged block template), but it’s unlikely to happen unless the pool software is too aggressive to request the block mining info from the kernel under some misbehave settings.

After upgrading to 1.6.1, this problem became more serious.

After submit_block, the result should be returned:

Unable to submit block

OR

block submitted via api

But, often there are neither of these.

I looked at the source code of node, the function is: modApiServer/src/org/aion/api/server/rpc3/AionChainHolder.java Line 191:

public boolean submitBlock

Neither logSealedBlock nor logFailedSealedBlock is executed, but it returns true.

So why does this happen? Can this problem be solved?
