DFS208I LMSG D/S LIMIT REACHED. MUST REBUILD.
Explanation
A record has been allocated within the shutdown area on the IMS.LGMSG system data set.
System action
An internal /CHE DUMPQ command has been initiated and in most cases, the system shuts down. In an XRF environment, a /CHE SNAPQ is initiated if there are VSO areas that have I/O tolerated data, and the system does not shut down.
Operator response
(z/OS® system operator) If the system shuts down, increase the space allocation for the IMS.LGMSG system data set and restart from the DUMPQ checkpoint which follows the message. The secondary allocation is not normally applicable to IMS queue data sets. The FORMAT parameter must be used to reformat this data set during restart.If a SNAPQ has been issued, the system continues to run, but it approaches the threshold value on the queue data set. If the system abends, increase the queue data set allocation and restart the system from the SNAPQ checkpoint using the /ERE BUILDQ command.
