Hi all,

I am working on Red hat Linux 2.6 and I am trying to compile some java files and when I am trying to do it,it compiles some file and then became hang up and doesn't allow me to do any operation..

I write one ksh script to compile all files by this script and move those file in specific directory.Output of this script is--

Hi,
I'm not a Java expert, but it looks like you need to check these errors:

Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

When your system hangs, can open a remote (ssh) session from another system?
System can hang for several reasons, memory, resources, hard disk, or your system is just busy compiling your Java programs. I'd also like to suggest that you post your system details, like memory, Redhat version and release

uname -a
cat /etc/redhat-release

Your java version may also helpful. You also try running top on another terminal while you are try to compile your Java code.
