Apr 8 05:42:59 HOST init: serial main process (10257) terminated with status 1
Apr 8 05:42:59 HOST init: serial main process ended, respawning
The issue is that serial main process terminates and respawns. This article provides a resolution for this issue.
Root Cause
The hardware serial port is not available to the underlying ExOS causing the software driver to crash and be respawned.
Resolution
Currently, the only resolution is to reboot the appliance.
