Re: Unexplained intermittent CAN / 2CAN Jaguar problems at GSR
1511 also saw similar failures during our time at FLR this past weekend. Fortunately for us this never manifested out on the playing field, only when testing in our pit.

I was able to attach the Windriver debugger a few times when we caught the error and have some technical details to compile and share with the developers (on my list of stuff to do hopefully today).

It appears to be almost certainly a race condition during startup whereby when the failure is tripped a task initiated for CAN handling is terminating due to following a bad pointer.

For completeness, our setup is serial/black jag based, all black jags in chain. C++ with latest (2/16) update, cRIO with image v28.
