Describe the bug
When the server dump command is run on the IBM i platform in QSH, it fails with a message similar to this one:

/QIBM/ProdData/WebSphere/LibertyServer/V22.0.0.13/Base/bin/server dump  dumptest

Dumping server dumptest.                                                                         
The command introspect#23.01.20_20.22.52 failed because of a communication error with the server.
