I'm consistently getting the below errors. What stands out is the "inconsistent hash" error, seemingly causing the workers to crash. The hash of the block header and this of the local hash seem to differ. I have no idea what this means though. Does anyone know how to solve this issue?

I was able to solve the issue myself. My node had rejected a seemingly valid block. I found this out by listing the rejected blocks of the node: 

tezos-admin-client list rejected blocks

Output:
Hash: BLqhrPaH6WQtVYZssbonME7DPiQLTvZyidkYa8dvAxxoeTsnVKD
Level: 356181
Error:
Inconsistent hash:
  local: CoWYi7Nmm91pS8ZNXscNTt6uBpNdaWtpantEc3HcV3XASYEVriNS
  block_header: CoVHuYH6TpDbJjXFqRsZXichbxdnvqWrDSaGpjVAsJRknAMk8Lkq

So the node rejected the block due to the different hashes of the headers and was not able to catch up, because it likely rejected a valid block.

I solved this issue by unmarking the block: 

tezos-admin-client unmark invalid BLqhrPaH6WQtVYZssbonME7DPiQLTvZyidkYa8dvAxxoeTsnVKD

Output: 
Block BLqhrPaH6WQtVYZssbonME7DPiQLTvZyidkYa8dvAxxoeTsnVKD no longer marked invalid.

I still have no idea why this happened.

  • Hmmm... I tried this but I got zero invalid blocks.

  • Then it's not the same issue as described above.
