Error description
CMAS or MAS may fail with messages: . EYUXC0023S applid Maximum data cache limit has been reached for QUE cache EYUXC0024S applid The CMAS is terminating due to a previous error with the Cache component . The CMAS trace will contain many exceptions with debug text NLS4FAIL and pointid 190. . The MASes will contain abend messages similar to : .

Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex/SM V3R1M0 Users * **************************************************************** * PROBLEM DESCRIPTION: QUE dataspace storage will be orphaned * * when an abend occurs in method EYU0NLS4 * * (NLS4) in a MAS. If the abend occurs * * often enough, this can result in * * auxiliary storage shortages on the LPAR * * where the abends occur or various CPSM * * dataspace storage shortage related * * messages issued by any CMAS or MAS * * running on the LPAR. * * * * Possible messages are: * * * * EYUXC0016S * * EYUXC0021S * * EYUXC0022S * * EYUXC0023S * * EYUXC0024S (CMAS only) * * * * Note that any CMAS that issues message * * EYUXC0024S will terminate after issuing * * the message. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all MASes must be restarted. Note * * that the restarts do not need to occur at * * the same time. * **************************************************************** When method EYU0NLS4 (NLS4) is called to process a CICS statistics record for CPSM, it allocates a work queue to store information it collects from the statistics record. Since NLS4 does not have a local recovery routine, if an abend occurs in NLS4, CPSM handle abend recovery (module EYU9XLRV) will return control to NLS4's caller after collecting documentation for the abend. As a result, the queue won't be freed, and resources allocated for the queue in the QUE dataspace will be orphaned. If the abend occurs often enough, this can lead to the problems documented above.
Problem conclusion
NLS4 has been updated to include a local recovery routine. As a result, EYU9XLRV will return control to the local recovery routine after collecting documentation for the abend. In the local recovery routine, NLS4 will free the work queue, issue an exception trace with a debug text of "NLS4Abnd" and a trace point Id of 26, and return to its caller with a Response of EXCEPTION and a Reason of METHOD_FAILED.
