CSCvp94349 - cat9300 crashed with PuntInject Keepalive Process

[JT43]

C9300-48P, I have 10 of these switches and all except one are OK.

One at ios 17.6.1r[fc2] keeps counting to "keepalive not received for 300 seconds" then crashes to "iosxe_infra2-fatal_no_punt_keepalive" then message "critical process crash" appears and sometimes (but not always) reboots. 

How do I fix this please?

Hello,

    The known fixed release for this bug CSCvp94349  is Fuji-16.9.2.  If you are at 17.6.1r either is not this Bug or Cisco did not fix the Bug (Both alternative is possible).

  If I were you I  would move to .17.06.04.

TAC concluded that this is a hardware fault and they kindly replaced the switch.
