Description (partial)

IPFIB process crash.

VOBJ has list of RNHs and CNHs. PFX points to a VOBJ. When ever the VOBJ is updated/deleted, all the corresponding RNHs and CNHs need to be updated. A vobj_delete, can trigger a RNH delete, which will trigger another VOBJ delete, for the same VOBJ. this cyclic dependency needs to be broken. Else we will try to double free  memory.
