I am trying to run a java application on a remote machine with the control
panel appearing on my hamm 2.0.36 Debian box. It used to work on a
different, pre-libc6 Debian box. It presently works on a Solaris machine,
invoking the program via ssh, but when I try to start the program running
via ssh on my Debian machine, I get a core dump. I know that access to
the X server is not the problem, since I can run xterm in the secure shell
and have a window pop up on my screen. Can anyone think of what might be
causing the problem?
Here's the guts:
bash$ /usr/local/java/bin/java ChatServer 6119
