I haven't been able to get to happen when using "chroot /", but here's output
from one of my sessions that did reproduce the "cannot allocate" problem:
nyap:jpmpsdev@NYAP:~> chroot /view/nyap-tig-du
nyap:jpmpsdev@NYAP:~> ls

.bash_history .emacs .saves-670-NYAP~ lisp/
.bashrc .emacs~ .viminfo msfe/

Can you give me some hints as to how I can track this down any further, please?
Thanks,

What is the chroot command that you're using "chroot /"? Since this actually
does nothing at all now it would be surprising if it had any effect on any
commands.
Details in bug reports are always a necessity if you want solutions.
