transaction %d in block %d has skipped validation

Error message

transaction %d in block %d has skipped validation

What it means

allValidated post-check: after block validation some transaction validation-code flags were never set, meaning those transactions were skipped without a verdict — an internal validator inconsistency rather than a per-transaction failure.

Solutions

1. Check peer logs for which tx indexes were skipped and why (e.g. MVCC validation or plugin errors)
2. Restart/redeploy the peer if the validator itself is misconfigured (e.g. missing validation plugin)
