Linux Program calling NetVault for Teradata Backup

Apologies if this is in the wrong forum. Please diirect me to the correct one if this is so.

We have a NetVault event called 'Prod_Root_Trigger' that is triggered as below.
We seem to get intermittant errors from this command with an error as follows:

Failed to start a CLI session - Failed to get connect or error message

function backup_submit
{
if [ $NETVAULT_FLAG = "Y" ]
then
echo "#### Submit the backup"
/usr/netvault/bin/nvtrigger -server ${Netvault_Server} -wait ${SYS_NAME}_root_trigger
else
echo "#### Netvault Run Flag set to N , backup not submitted."
fi
}

Any ideas what might be causing this?
