BackupExec on Linux : /opt/VRTSralus/bin/beremote daemon stops unexpectedly

When making backups of my linux server, I can have errors on open files generating errors... but the issue is that the backupexec remote agent stops running and then is unavailable for the next job.
A workaround consists in checking every hour (in this example) if the agent daemon (/opt/VRTSralus/bin/beremote) is still running, and if stopped, restart it.

Create the following script file (/root/restartRalus.sh) :

if [ -f /bin/grep ]
then
  PID=`/bin/ps -e | /bin/grep beremote | /bin/sed -e 's/^ *//' -e 's/ .*//'`
else
  PID=`/usr/bin/ps -e | /usr/bin/grep beremote | /usr/bin/sed -e 's/^ *//' -e 's/ .*//'`
fi

if [ "${PID}" = "" ]
then
  /etc/init.d/VRTSralus.init start
fi


And execute it every hour for example :
> crontab -e
> 0 * * * * sh /root/restartRalus.sh
