There is a medium probability that the HPE 6600 & HSR6800 Router LPU Modules listed in the Scope section below, when installed in a HPE FlexNetwork HSR680X Router Chassis may reboot. This will only occur if the Router Chassis software has been upgraded to R3303P31 through R3303P37 inclusive. An unexpected reboot of the LPU modules may be detected if the correct conditions are met. The reboot event will be displayed on the console/VTY interface when this issue occurs.This issue will be triggered when the HPE FlexNetwork HSR680X Router Chassis MPU is running software versions R3303P31 through R3303P37 inclusive, and multicast packets are being forwarded from the affected LPU modules to the FIP-600 Flexible Interface Platform Router Module (JG360A). The following information will be displayed on the console/VTY interface when this issue occurs:[HPE]================= exception info (no: 0) =================Exception Number: 0x02Exception Name: TLB miss exception (load or instruction fetch)Exception Instruction: 0x80767B38Exception Slot: 0Exception VCpu: 19Exception Task: N/A (TID: -1)Exception Stack Base: 0x828f9ffcException Stack Top: 0x828f9940Exception Time: 2017-09-18 09:52:47Exception Tick: 0x22(CPU Tick High) 0xb0879c2c (CPU Tick Low)After the affected LPU module is rebooted, the exception will also be recorded in the diagnostic-information as follows:=======================================================================================display exception information slot 0======================================================================================================== exception info (no: 0) =================Exception Number: 0x02Exception Name: TLB miss exception (load or instruction fetch)Exception Instruction: 0x80767B38Exception Slot: 0Exception VCpu: 19Exception Task: N/A (TID: -1)Exception Stack Base: 0x828f9ffcException Stack Top: 0x828f9940Exception Time: 2017-09-18 09:52:47Exception Tick: 0x22(CPU Tick High) 0xb0879c2c (CPU Tick Low)
