There is a command check you can run from any waimea prompt as user nirspec to check the health of communications via the fibers to the transputers. You can run this command only when the server is not running. Note that the command sometimes takes 20 or 30 seconds to run.
Here is what the output of check should look like when the fibers are ok (and the servers are off):

Here is what check will output if one or more of the server processes are still running, or there is a problem with communications via the fibers:
12:53pm waimea:nirspec> check Error : can't access resource [c0t4l0] Error - check - cannot access root transputer (result = -1).
