What you gave was was called a "stack trace". Stack traces are generated when exceptions are thrown but not caught (they are caught by the Java VM and generally printed to standard output) or when a thread dump is requested. If you got a thread dump, then you must have requested one. As I recall, there didn't seem to be anything wrong with the dump you showed. Why don't you tell us more about what is happening? -chris
