            ALERT: Because the oldest logical log (logid) contains records from an open transaction (transaction_address), the server is attempting to dynamically add a log file. But there is no space available. Please add a DBspace or chunk. Then complete the transaction as soon as possible.
            ALERT: The oldest logical log (logid) contains records from an open transaction (transaction_address). Logical logging will remain blocked until a log file is added. Add the log file with the onparams -a command, using the -i (insert) option, as in: onparams -a -d dbspace -s size -i. Then complete the transaction as soon as possible.
            Log file logid has been pre-dropped. It will be deleted from the log list and its space can be reused once you take level-0 archives of all BLOBspaces, Smart BLOBspaces and non-temporary DBspaces.
