Thanks for the file. It's helpful.

I have found three Cisco Bug IDs: CSCvc69872, CSCvc34329 & CSCva07166

Here are your options:

Raise a TAC Case to accurately determine what caused the crash (and verify if either one of the three is the correct Bug ID or someone new); and/or
Upgrade the IOS

Do note that Cisco has announced that the EoS for the 15.2(2)SY and the recommended upgrade path is 15.4(1)SY train. However, I am currently testing 15.4(1)SY1 & 15.4(1)SY2 in several 6840 models and all of them have elevated CPU or higher-than-normal due to "slcp process". I have an existing TAC case.

Thanks for your helpful feedback, we upgraded the code to 15.2.(2) SY3.
