FW: UI getting "killed" randomely on Fedora machines

[Brian D. McGrew]

Good morning all,

We're seeing a problem where an application is being killed from what
appears to be an out of memory issue.  Can anyone offer any insight on
this for me?

Thanks!

Why are we getting out of memory?  Are you running with the JEditor?
