UBR10k log event


l'm receiving this log since I update my IOS to: ubr10k4-k9p6u2-mz.122-33.SCJ2a.bin

SLOT 5/0: %JIB3_US_FAUNA-3-JIB3_US_SEU_INT: JIB3_US_FAUNA_SINGLE_BIT_SEU_INT event; cri_bit_info 0x6DFC0220; ctrl_status 0x0000152A

Only slot 5/0 are affect.

any idea ?

Interface Cable5/0/0
Hardware is MC2020V

Upstream MAC Processor Powered by Jib3 Upstream FPGA Complex
Jib3 Upstream FPGA is Initialized

So this looks like a single

So this looks like a single bit is off. Being an SEU (Single Event Upset), this should only occur once or very infrequently. Are you seeing many of these in the logs? If so, then maybe a reseat of the card would be the first thing to try.
