gmake[2]: *** [settings.mk:446: resultsSummary] Terminated

All tests finished, however when doing the resultsSummary the process was terminated without the reason, which will cause no test results available and fail the test job.

Start with the Jenkins console output and inspect settings.mk:446, makefile:50, and parallelList.mk:14 to trace the terminated resultsSummary and testList targets. Check testEnv.mk and the AIX test job context; done means identifying why termination occurs and ensuring test results remain available for the job.
