Hi Mark,

Yes I did the upgrade and the problem still happening continuously. I rollback to the standard version.

Ive checked the release guide i dont see any matching bug this could be hardware issue too, is it always switch 2 in the loggs

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/3e/release_notes/OL3262101.html

have you ran the show tech through the CLi analyzer to see if any known bugs show up or hardware issues , you can post it i can run it either

do you have TAC support if it requires an RMA ?

What happens if you reboot switch member 2?

[denilson.mota]

What makes you think that is switch number 2? According with the log is referring to switch MEMBER and 2 process kernel.

I think it is read as "MEMBER: 2 process kernel".  Member 2.
