CSCuy38033 - NFEs on same FM might pick up different egress intf for ECMP hash

Hello, looking for more guidance on this bug and the provided "workarounds". The first suggestion from Cisco is to disable the fabric module, my question on this is what kind of performance impact would this have? The switch we are seeing this on is a core switch(1 of 2 in a pair) and all our datacenter traffic traverses this pair of switches. Second suggestion is to issue the following command: port-channel load-balance internal rtag7  Again, my question is what kind of impact will this have on the existing traffic traversing the switch? And would we need to issue the command on both switches. Obviously we do not want to implement the workaround and impact production traffic adversely. Thank you.
