Remove Scripts That Bounce the Pass-Through
Process
In order to correct some issues associated with the Pass-Through process on the
DNCS, some sites have been regularly bouncing this process through scripts that
reside in the crontab file. SR 2.8.1/3.8.1/4.3.1 contains software that corrects issues
associated with the Pass-Through process. Therefore, after the upgrade, you should
remove any entries in the crontab file that reference scripts that bounce the Pass-
Through process. The instructions in this section guide you through the process of
removing these references.
