Missing a Block = Encountered Block Num Collision (Switching to Fork)

justyy -

When a witness production node misses a block due to its inability to respond and generate it within the 3-second timeframe, the subsequent witness receives the opportunity to produce the block. If the original node then attempts to generate a block in the next 3 seconds, this can result in a block collision and, ultimately, cause the node to switch to a fork.

Possible reasons for missing a block include:

  1. High network latency.
  2. steemd crashes.
  3. Disk corruption or a full disk.

Steem to the Moon🚀!
