Why does the sosreport command hang?

Issue

• This issue happens in sos-2.2-* (This does not happen in sos-3.2 or later and sos-1.7 or less because sosreport shows the name of plugins while running)

• When running the command sosreport to gather information on a system which has an issue, the sosreport hangs on an unknown plugin process.

• The screen shows a message similar to the following:

 Running plugins. Please wait ...
