Can't run a full node

when i run a node use aurad start, it trigger an issus

Claims and Mint module

Claims and Mint module serves a chain tokenomics. These two modules are present in almost all serious chains.

Mint module: mint module governs the flow of newly created token per block.

Per 1000 token / block for example. How much goes to community pool, how much goes to staking, how much goes to artist incentives, should some be burned, ...
This is an important module to govern the flow of token.

Claims module: free airdrop is just worst. Claims, however, is way better. It incentivies airdropped account to try-out the chain use cases.

writing module to custom folder can lead to complexity in proto generation

By this point, I still don't understand why Aura decides to write custom module in custom folder. There is a specific reason why it is placed in x folder in the first place.

Protobuf defines the datastructure of every cosmos module. When generating go files for protobuf, .pb.go files will be generated into x/module/types. By writing custom module to custom folder, it will complicate things such as making aura source incompatible with ignite cli. How so?

"ignite generate proto-go" for generating go files bases on protobuf will write to folder x
"ignite scaffold module" for creating new custom module will also write to folder x

Process fault/crash and refused to resume

I woke up this morning with my validator being down. After I inspected, only peer gossip was being shown in the log. I restarted the service and got this:

To resolve the issue I performed an unsafe-reset-all and did a fresh state sync.
Any idea on what may have initially caused it? I run several nodes on one server. This was the only one to have an issue. I would expect to see more of the nodes down if it was a drive or some other type of possible hardware issue.

When viewing event smart_account_tx from this tx on serenity, I got that value
