Hi Otto,

It doesn't look like there's anything in your ulimits that would
interfere with sbcl. It's possible that virtuozzo itself imposes some
kind of limit on virtual memory. Alternatively something else just
happens to be sitting in the range of memory we try to use. To test
this out, try starting sbcl under gdb, putting a breakpoint on main,
and running the program. When gdb stops at the breakpoint, look at the
file /proc/`pidof sbcl`/maps .

If something else is in the requested space (0x09000000 to 0x29000000)
we can't use it and you'll have to alter a file (
src/compiler/x86/parms.lisp variables dynamic-space-start and
dynamic-space-end in the #!+linux section ) and rebuild SBCL from
another, working host.
