i enabled detailed logging for controller availability logging, and now our diagnostic display sometimes stops updating while the log folder is busy.
We're watching Fairino FR10 in a maintenance station collecting read-only status, with an inspection plate as a reference.
The cell controls are separate. i suspect synchronous file writes, but i haven't ruled out communication delays.
Can synchronous log writes explain these freezes? (Fairino FR10, controller availability logging)

Can you replay saved responses offline with a slow log destination? Measure receipt and processing separately

@YasminChen1137 It does. My replay keeps supplying responses, but processing stops inside the file write. Finally, something i can reproduce.

Try a separate writer with a bounded queue in that replay. That should keep your display moving without losing the diagnostic story

@YasminChen1137 i've reproduced a logging stall offline. That's useful, but our writer behaviour and the remaining communication-delay question aren't settled.

One reproducible stall is useful progress. The writer and communication questions can reasonably stay open
