DFS2077I DATA IS LONGER THAN BUFFER NODE x (USER y).
Explanation
An error was encountered while attempting to move data into a buffer. Either the segment received was larger than the SEGSIZE specified in the IMS system definition, or a VLVB block count was larger than the remaining buffer size.
System action
The session for the node or user is terminated. The data that was to be blocked was lost.

Redefine the buffer size and regenerate the IMS system—or make sure the data generated for output is not longer than the defined buffer.
