The proc filesystem is not mounted. proc is an interface of the kernel to
user programs, in the appearance of a file systems.
Furthermore, any file system, except / , is not mounted.
To mount the, run:
mount -a

To see exactly what is being run by a shell script, add somewhere in it
the line:
set -x
This is disabled by:
set +x
if you want to make just one part of the script verbose.
Note that if the whole script will run in verbose mode, it will run
slower.

Is this related to timeing somehow?
If the above 'set -x' trick won't help, try adding a 'sleep 5' ("sleep for
5 seconds"). Maybe this is related to something that blows up after x
seconds. Either software-related or hardware related.
