Hi, do you have already seen this documents?

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/3se/multicast/configuration_guide/b_mc_3se_3850_cg/b_mc_3se_3850_cg_chapter_010100.html

Try to disable multicast or filter it.

To be onest I don't know if it works but I suggest you to try.

There are bugs about cpu utilization and mdns (eg. CSCui63462, CSCun63678) so you can try to load a different IOS or open a TAC case.

Regards.
