Goldengate GGSCI does not respond to commands

Getting more hands-on with Oracle GoldenGate lately I have been keeping an eye open for those types of issues on My Oracle Support, and article "Goldengate GGSCI Commands Do Not Respond" via note ID 2076372.1 strikes me as odd that an NFS mount is getting locked to prevent GGSCI from responding!  Check out the associated article about NFS setup too, just to make sure you have everything setup correctly!
