Unable to create SMB share with webui

I attempted to create smb share and receive error message:

Your share was not created

Error #1: did not get response from server

I then went to the command line and was able to create my share.  A little digging and I found the following:

Resolution: seems the webui service stopped responding to smb calls for some reason.  The fix is to run the following command:

isi services isi_webui disable

followed by

isi services isi_webui enable

Share creation was then possible from webui
