Symptom

If we have a key of 128 character or more and you upgrade to 16.3.5 or 16.6.1, switch will crash and get stuck in rolling reboot. When attempting to configure 'server-key' on 16.3.5/16.6.1 switch crashes with PMAN errors as below: Oct 31 07:09:48.601 R0/0: %PMAN-3-PROCHOLDDOWN: The process smd has been helddown (rc 134) Oct 31 07:09:48.628: %PMAN-3-PROCHOLDDOWN:Switch 1 R0/0: pman.sh: The process smd has been helddown (rc 134) Oct 31 07:09:49.284: %PMAN-0-PROCFAILCRIT:Switch 1 R0/0: pvp.sh: A critical process smd has failed (rc 134) Oct 31 07:09:49.901: %PMAN-3-RELOAD_SYSTEM:Switch 1 R0/0: pvp.sh: Reloading: Peer switch is not standby ready.
