I have software running on Jetson AGX using the Jetson Argus libraries. As part of my code, I have a CaptureSession object which I interface cast to an IEventProvider and call methods like createEventQueue.
I have this code (including this cast and createEventQueue call) running in a loop for several days without issue. However intermittently (once per several days) I’ll get a “pure virtual method called” crash. I have observed this crash within gdb, and the stack trace has boiled it down to the following pseudocode.
What would cause this call to intermittently fail? I have some theory, e.g., about a flaky hardware connection causing the CaptureSession object to be deleted or put in an invalid state, but it’s hard to speculate into the internals of drivers and NVArgus.
fixed clock rates in order to ignore system level clock configuration.
we may still need to understand the error logs.
you may try setting up a terminal to keep gathering the logs. i.e. $ dmesg --follow.
please share complete failure logs with respect to the “pure virtual method called” crash.
