This is a very minor nitpick, and unlikely to be the cause of the
problem, but there's nothing in that script that requires Bash. Use
`#!/bin/sh` instead. It's the default execution shell for the system. In
fact, since you specify the full path to snmpwalk in the script you
could remove the shebang altogether and just run `sh /root/snmpwalk.sh`
in the cron job.
Though it's probably not the solution (I assume you have Bash
installed), using the native shell rather than a third-party shell would
at least rule out a possible cause.
