OBSW Parameter Poller produces error
View options
Summary
The Supervisor in flight produced a bunch of
Steps to reproduce
Unknown. Possibly running Supervisor for extended period with SPP Bridge offline and then starting SPP Bridge could trigger it. See FM System Journal in the period of 2022-05-20 03:00:00 - 2022-05-22 19:05:37.
What is the current bug behavior?
The Supervisor OBSW Parameter Poller produced an following error every 5 seconds. Note it happened after SPP Bridge was inactive for at least 2 hours.
What is the expected correct behavior?
No error produced.

May 22, 2022 7:05:37 PM esa.mo.mal.impl.MessageSend initiateSynchronousInteraction Possible fixes
Investigation pending. To be observed if Supervisor restart fixes it. Furthermore, we should explore the following options:
- Throttle the verbosity of logging by the Supervisor (look into different options)
- Fix the addDefinition Error response encoding in OBSW (or decoding in NMF) as they clearly mismatch
Link items together to show that they're related or that one is blocking others.
