Current Behavior

In some rare race condition, loading the json file using lcls-twincat-pmps may fail.

You can recover this pretty easily using the pmpdb client tool:

(pcds-5.8.1)zlentz@rix-console:~$ pmpsdb reload plc-kfe-rix-motion

See #211 (comment)

Expected Behavior

It should work every time, maybe it should automatically retry a couple times if it fails?

Context / environment

Happened once in prod

Steps to Reproduce (for bugs)

Unknown

Suggested Solution

Retry a few times?
