It's failing with the skins that ask for a lot of shadow memory by
the looks of it, which probably means the large mmaps are failing
which is something I saw once but was unable to reproduce after a
reboot.
I think some kernels reject vaery large mmaps under certain sorts
of memory starvation condition or something - there is a bug for it
on the bug tracker somewhere.
If you're not already using the latest kernel for that version
of RH then I'd suggest upgrading or even just trying a reboot of
the machine.
