Hi John,

Did you by chance happen to have Windriver's target debugger connection open when this occurred in your pits? If so, did it report any abnormal terminations or errors?

If not, you might consider doing so as this can provide a wealth of information when things go awry. You don't have to be "debugging" the code at the time -- you can be running an "deployed" program. The nice part about it is that it will report any task failures/terminations to you as well as stack information if available.

Are you able to go into a bit more detail on what your dashboard task is doing exactly? Particularly in relation to CANJaguar objects, as well as frequency of iteration.
We send dashboard data during disable as well, but do it as part of the normal disable processing routine rather than as a separate task.
