Issue/Introduction

An svcdump was generated at the time a temporary shutdown of Top Secret was performed on 2 systems. Here are the errors:

Resolution

The dump shows normal health check shutdown being processed. Health Checker (HC) subtasks were posted for shutdown and the main HC task (under Top Secret) set a timer and waited. When that timer expired, a series of checks were done. The first was attempting to pause/release the subtask. It got an RC=4 (invalid token) because this had already been done as part of the shutdown. Next it verifies if IBM's HZSPROC is still active (it was not). It then checks a flag indicating the subtask has completed all of its cleanup and should be complete. This was set, however the TCB itself was still running. From the systrace, it was processing end of task routines, and some SSI hooks. All of this processing appears to have "delayed" shutdown, resulting in the hard DETACH of the task. None of this extra processing appears to be abnormal.

Other than a dump being generated, it had no impact on functionality.

None of that extraneous processing is under the control of Top Secret or CA-Health Checker.
