Cisco Cisco IOS Software Release 15.2(3)E 릴리즈 노트

When a logging discriminator is configured and applied to a device, memory leak is seen under 
heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In 
extreme cases, the device may crash. As a workaround, disable the logging discriminator on the 
device.

Standalone web-based authentication fails if the switch port is configured without any port ACL.

from multiple vendors.
