JNLMEMDSK, Journal file unsynchronized with the journal buffer. Journaling closed for xxxx.
Run Time Error: This indicates that the structures in the journal buffer reflect an out-of-design situation. As a result, GT.M has shut down journaling for the xxxx region.
Action: Review the accompanying message(s) and take appropriate action. After the cause is resolved, to reestablish durability, perform a MUPIP BACKUP that turns journaling back on. Once the system is backup and running, contact your GT.M support channel with operator log information and any additional information that you feel is relevant for further diagnosis.
