Gluu Server shouldn't share any other application

[mzico]

Please put a tag in "Installation" page:

"Gluu Server should be installed in vanilla VM / Server. Sharing Gluu Server's resources with other pre-installed software might cause various issues. Other supporting software like external logger or monitoring software can be installed after the completion of Gluu Server installation but administrator need to make sure that other software shouldn't disturb Gluu server's mandatory ports and resources"
