Description (partial)

Symptom:
Symptoms:

Severe:
* Users can see many instances of scripts being active.
* many processes of command 'lsof'
* the DLP Output folder continues to grow

Mild:
* Event Vision fills with errors/warnings regarding failure to move files from the DLP Output folder
     for example: Checksum compare is failing between /infobright_dlp/ifb_dlp_data/DLP_Output_Files and /infobright_backup/ifb_backup
* Event Vision warnings may not be very frequent maybe 4-5 times daily.

Conditions:
there are number of scripts being executed as root from the crontab.  The scripts have no protections against long runs of the script.  The lack of protection leads to severe CPU and filesystem troubles.

This bug is for  /var/adm/cisco/infobright/move_dlp_files.sh ; however the scripts in the same folder should be checked if any protections need to be used for their executions

The severe symptoms occur because of a very large backlog which can be because of systems being down for a long time or connectivity issues to the active gateway.
