Any indicator in the dump about the cause ? (I have NO experience in analysing cisco dumps)

Best and thanks,

- Usually this due to software bug(s) , try a more recent software release for your platform, if applicable and or choose a gold-starred release.

Sounds like a bug with the software that caused a memory leak to the "SNMP ENGINE".

NOTE: Chassis is running on a "T" train.

sorry i didn't get that "Chassis is running on a "T" train"

hi

"T" train refers to the IOS software naming convention. You can more details about CIsco IOS naming conventions at the below link

Regarding your router reload, basically the router has crashed due to some software defects. From the crash decodes it can be seen that SNMP process was trying to access the memory during which the crash occurred.

Can you provide with the show tech of the device ?
