Cisco devices configured with logging discriminator may experience a memory leak or crash. When a logging
discriminator is configured and applied to a device, memory leak is observed under heavy syslog or debug output. The
rate of the leak is dependent on the number of logs being produced. In extreme cases, it is possible that the device might
crash. To avoid memory leak, disable the logging discriminator feature.
