The operator started the real storage manager (RSM) component trace and requested that a trace data space be used to contain the trace data. RSM lost some of the trace entries because it was creating trace entries faster than it could copy them from central storage to the trace data space.
The RSM component trace continues. Trace entries continue to be lost until RSM finishes copying the trace buffers to the data space. RSM then re-uses the buffers for newer trace entries.
Notify the system programmer.
If the RSM trace successfully captured enough data to diagnose the problem, the message indicates no problem. When the trace is turned off, examine the trace entries in the dump. The trace data gives the number of entries lost.
