Hi, I have a sample applet program which spawns a thread that prints the current date and time on a JLabel element. The applet runs fine for a few hours and then hangs. This applet is run on a firefox browser on a Solaris VDI platform. Note that the same applet runs fine on an IE browser of firefox browser on Windows OS. Attached is the source code and thread-dump output of the applet after it hangs. Any help to figure out the root cause of this issue is appreciated. thread-dump_out.txt ClockWithSleep1_java.txt Thanks, Prasad thread-dump_out.txt ClockWithSleep1_java.txt    More>>
