linux kde reliable for commercial app?

[Joseph]

Hi
I'm coding a commercial application that will run on linux. They system is
a java program that will run within KDE. I know linux is reliable as it's
used as a server, but how reliable is kde ? I need the application to run
within KDE continously (night and day, all the time). It will be okay if
it crashes occasionally, but not often. How often will a program crash in
the KDE? what other reliable operating systems are out there that will
support a java gui program intended to run continuously?

thanks
Joseph
