What I will do for this model ? Shall I use 15.0(2)SE12?
Is it happening due to IOS bug?

Hi Leo
You are right it should not repeat.
I have read some document where it is telling that Due to IOS bug it may happens.Here is my confusion .I am trying to understand that, for me is it happening due to wrong process of IOS upgrade.
Request you please correct my understanding
