Does this private key have a passphrase?

First question: what did the output say?  Any output from the cron job
should have been mailed to you.  If you don't have a mail reader set up
on this machine, try "less /var/mail/$LOGNAME" or something.  If you
don't have local mail delivery set up, fix that.

Second question: if the key has a passphrase, are you using an ssh-agent
to invoke it normally?  The cron job won't have access to your ssh-agent,
not without a bunch of additional setup.

For automated jobs, you usually need the private key to NOT have a
passphrase.  And yes, this is a large security concern.  You'll have
to balance your security needs against your application needs.
