Description (partial)

When Bidirectional Forward Detection (BFD) is enabled, issuing certain CLI commands that are not premption safe may cause the device to restart.  This condition has been seen when issuing commands such as "show mem" or"show mem frag detail".

The issue may occur if BFD is enabled on a device that utilizes Pseudo Preemption to implement this feature.  The device must be running an affected software build.
