                        Hi Levente,<br>
                        <br>
                        I directed stdout to a file and prior to the
                        freeze, did:<br>
                        <br>
                        pkill -USR1 -n -x squeak<br>
                        <br>
                        a few times and noticed "stack overflow"
                        mentioned twice. After the freeze,<br>
                        pkill sent nothing else to stdout. Maybe
                        something in stderr? I'll try<br>
                        again and concatenate stderr to the end of
                        stdout. Meanwhile, the file with<br>
                        the stack overflows is attached.<br>
                        <br>
                        Thanks for the help.<br>
                        <br>
                          - Dan<br>

                          Hi Dan,<br>
                          You can send the USR1 signal to the VM process
                          to make it write some debug<br>
                          information to the console. With this
