We've got a (large) Java Swing application that's demonstrating some very strange behavior. If the computer running it is left idle (no mouse or keyboard input) for a sufficiently long time (varies between an hour or so and a couple of days), the Swing display sometimes stops updating totally (we've got, among other things, a clock shown on-screen that stops updating) until the user moves the mouse. Once the mouse has been moved, our application seems to function normally. (Creating and removing a window from another application also causes the display to start updating again; keyboard input doesn't appear to be sufficient.). There are no errors in /var/log/messages etc.
Following are the software environments:
a.. RHEL5.0 distro, but kernel was upgraded to 18.104.22.168
· JDK 1.6.0_07
Any assitance you can provide is greatly appreciated.
