Guys,

We have a Java app the is falling over on Aix returning 'Exit Code 255'
- is there a way to find out what is causing this ?

My gut feel is that it could be memory related, is there more
information available about what 255 actually means ?...i'm hoping it's
not just a generic exit on fail.

TIA,
Mike.

Is the Java virtual machine up and running when the error occurs?
I mean, does the JVM fail to start or does it terminate after some time
of operation, returning the exit code?

Are there any output, stacktraces, core files etc?

Please give more relevant information!

A Java program can return an arbitraty return code to the operating
system by calling the System.exit(int) method.

If that is what happens, you will have to ask the application programmer.

Yours,

Something somewhere is calling exit(-1), or the program is just exiting
without specifying a return value to the operating system and whatever
happens to be in memory at the time is returned as your exit code.
