Solution

The logs and the issue are seen when the remote shell cannot fetch host-OS info.
Below are the things to check when these log messages are seen:-

  1. Was the device recently upgraded?
  2. Any sudden/abnormal reboot of the device.


Ways to mitigate:-

  1.  Verify if the upgrade was not completed properly and re-initiate the upgrade on the device.
  2. If the device was not upgraded recently then power drain the device and monitor if the logs are seen again
  3. Please open a JTAC case if the logs are still seen after power-draining the device.
