  I'm working with ATAC tonight to get them a running kernel core dump
so they can look for root cause, but apparently disabling GRES,
committing, re-enabling GRES, and committing again, somehow can
temporarily resolve the issue (get the routes installed, I guess
?!?!).  Don't ask me how GRES has anything to do with it....
