Since > the log file contains no valid transactions, it is marked as corrupt and > renamed with the {{.corrupt}} suffix > - The sanity check in {{openLogsForWrite}} will refuse to open a new > in-progress log at the same txid. Failover does not proceed. -- This message is automatically generated by JIRA.
