As the message says, you have filled up the global/trail stack.
This area is where most of the runtime data structures of an
ECLiPSe program are allocated (see the user manual chapter
"Memory Organisation and Garbage Collection").

There are basically 2 possibilities:

1. you are accidentally allocating unlimited amounts of memory,
for example because a recursion does not terminate as expected.
Use the tracer to find out where it happens.

2. your program really requires that much memory: in that case,
start eclipse with a larger stack.  In a command-line eclipse
you do that by giving a -g option (e.g. -g 500M for 500 megabytes).
In tkeclipse, you open the Preference Editor, edit the Global/trail
stack size entry, save preferences, and restart tkeclipse.
