Whenever we reproduce the problem this error appears in the PCService.log.

ERROR | Model-Invoker-15         | 2021-10-04 18:59:05,536 |
      | Unmarshalling Error: Maximum Number of Child Elements limit (50000) Exceeded

The log is found in the (default path shown) /opt/CA/PerformanceCenter/PC/logs directory.


The amount of rows being returned for the query exceeds the default SOAP limit of 50000.

  3. Increase the amount of child elements allowed. (default paths shown)
