I need some help understanding these log messages.
I've been executing long-running tests to exercise stability for an object detection Python application built around the v3-rc4 library.
Failures with ping timeouts and reconnections happen as often as a few times an hour.
I've seen two reports of a device crash in two days of testing. As requested in the logging statement I sent the first report to Luxonis Support about a week ago (have not heard back).
Questions:
- What exactly is a device crash? This seems serious. Do we need to update firmware on a camera or perform some other intervention to keep it running continuously?
- How normal and expected are the ping timeouts and reconnections? Should we be changing settings somewhere or performing some kind of troubleshooting for more stable communication?
- Are reconnections fully automatic and restore detection networking functionality, etc.? Or, upon a reconnection is there something we need to do to ensure the pipeline is restored too?
