Cisco 3650 stacked, Denali, MPLS nodes, best practice?

Hi all, does anyone see an issue with using stacked 3650's as a single MPLS node with multiple 1 and 10g layer 3 interfaces across both stacks?

This seemed like a great idea at first, but I've been running into a number of issues including a number of FED_L3_ERRMSG error messages in the log that seem to be more than a cosmetic issue. Main issue that I'm having seems to be stuck routes. When links go up and down, it looks like the L3 adjacencies come up okay, but it seems like certain traffic just ends up getting lost even though routes look okay.

Can anyone share their thoughts or best practices in this situation? Do I just have bad hardware?
