Raise a Cisco TAC case.  The crash is due to a memory leak even when the router is running the latest version of the "M" train, 15.4(3)6a.

Thanks Leo.

i am afraid we do not have a tac support for routers. i believe this will effect all routers 860v. however, before on cisco software website the above image is stable image.
