The message says that an error has been detectedin a user node built on the Raspberry Pi and using a 500 GB SD card as storage so that there are no problems using it 24/7.
Bitcoin Blockchain Uses ConsistentPoW protocol (Proof-of-Work). This protocol is used to find a line of code that starts with a few zeros, around 19: these zeros reflect the complexity of the calculation and, as a consequence, the security of the transaction.
If a bitcoin transaction has only one 0 oreven a couple, as in this case, we can easily conclude that it took a little time to calculate the hash, and therefore there is a 99% chance that it was an attempt to attack bitcoin and push through an incorrect transaction.
Fortunately, the transaction was rejected by the specifiednode. This is a good example of how Bitcoin (BTC) and the PoW (Proof-of-Work) protocol proved to be resistant to any type of attack, even differing from the most famous 51% attack.
