Symptoms

Causes

After you upgrade the kernel of your Red Hat Enterprise Linux operating system, the Unix and Linux clients reboot for the following reasons:

• The clients have the CDR module installed.
• The subclients are using the Optimized Scan.

Resolution

1. On each subclient, disable the Optimized Scan.
