Description Aneesh Puttur 2022-02-14 18:58:47 UTC

Description of problem:
LinuxPTP daemon has the functionality to restart when the process dies.
But the process also force killed while there is a change in ptpconfig.
This was create multiple time socket errors when the event framework is used.



Version-Release number of selected component (if applicable):


Step to reproduce 
modify ptpconfig and reapply and monitor fast event logs(cloud-event-proxy)
The cloud event proxy recovers from this error but cause to delay in reading logs from the socket

time="2022-01-31T20:21:45Z" level=error msg="error reading socket input"




Actual results:
Shown twice
time="2022-01-31T20:21:45Z" level=error msg="error reading socket input"
time="2022-01-31T20:21:45Z" level=error msg="error reading socket input"


Expected results:
time="2022-01-31T20:21:45Z" level=error msg="error reading socket input"
You should see with zero times or not more than once
