I thought your image freezing might be related to the VM bug reported  
here: http://bugs.impara.de/view.php?id=4709. However, some tests I  
did recently show that the bug does not depend on the VM version but  
on the Linux kernel version 2.6.

1 - Squeak 3.9-9 VM, Linux 2.6 BUG
2 - Squeak 3.6-3 VM, Linux 2.6 BUG
3 - Squeak 3.7b-5 VM, Linux 2.4 OK
4 - Squeak 3.9-9 VM, Linux 2.4 OK

I updated the Mantis report with more details.

John, I tried what you suggest in this mail http:// 
008981.html. I attached the gc stats files to the Mantis report.

Keith, could you provide a gdb backtrace of a frozen image? Do you  
also see the problem when running with -mmap?
