hi, i have a qfx5110 device running as a layer3 gateway
After 1 month of deployment, the switch hangs twice in a row with these lines in the log
buf to ukern pkt:638 bad cookie magic id (possible memory corruption)
i'm not sure if this is a software or hardware error. i'm running version 21.3r3.s9
any advice please. thanks
