[JoySnow]

Get the following exceptions from "Insights Times and Errors Report 2024-03-05" :

count	component	request_id	exception
140843	insights.specs.Specs.ps_eo	some_request_id	ValueError("invalid literal for int() with base 10: ' 1'")
140843	insights.specs.Specs.sysctl	some_request_id	ValueError("invalid literal for int() with base 10: ' 1'")
57962	insights.specs.Specs.sysctl	some_request_id	ValueError("invalid literal for int() with base 10: 'callback 1'")
57962	insights.specs.Specs.ps_eo	some_request_id	ValueError("invalid literal for int() with base 10: 'callback 1'")

The ValueError was raised for parsing special input data of Specs.ps_eo, some example lines:

  PID  PPID COMMAND         NLWP
    1     0 systemd            1
  863     1 falcond            1
  865   863 falcon-sensor     29
3106 2 NFSv4 callback 1
20570   865 falco <defunct>    1
