There is currently no standard way defined for this.  In the past, we discussed having the provider report such errors to the EQ.  It shouldn't be hard to define that in the man pages, but it would still need to be implemented.  Such errors would be reported as best effort, though, with no guarantee that events would be written in all cases (e.g. remote system crashes, with no notifications sent).
