This issue is a known bug written up under bug fix number OS-484.
This issue has been resolved in the new Infrastructure agents released with the FMS version 5.6.2 . The current OS agents (5.5.4) will not have this issue addressed in future release.
It is suspected that the AppMonitor agent will have this same issue as it shares the same base code. The Guest Process agent (any version after 5.5.4) should be fine
