It is weird if the problem is with the number "5".  Why on earth would
"5" be special?

They might also try this shell script:

#! /bin/sh
exec 5>&-
exec 5> /tmp/foo.log
echo foo >&5
cat /tmp/foo.log

as it may be possible to work around the problem by closing 5 first.

Also, can they use "truss" or something like that on the failing process,
to see what system calls it is executing just before the failure?
