shutdown problem

[Penny Champine <p a champine express larc nasa gov>]

When I try to shutdown I get the following error:

[root server /etc]# shutdown -r now

Error in startup script: can't read "env(CMS_ROOT)": no such element in
array
    while executing
"set HOME $env(CMS_ROOT)"
    (file "/bin/shutdown" line 5)

I can shutdown the system if issue the /sbin/shutdown -r now command
instead of the /bin/shutdown command procedure.

the system is running:

Red Hat Linux release 6.2 (Zoot)
Kernel 2.2.15 on an i686

Any ideas?
