Symptoms
License messages in logging buffer and syslog
'set license'
'set logging'
'show logging buffer'
"UNKN[]: usmdb_keying.c() %% License Re-evaluate."
"UNKN[]: usmdb_keying.c() %% License DB task: update from unit time"
"UNKN[]: usmdb_keying.c() %% License DB check"

Cause
When a C2L3-LIC Advanced Router license has been configured (5828), "License" messages will appear in the output of a 'show logging buffer' command if both the "System" application and default severity have been set to "debug" level 8 ('set logging application System level 8', 'set logging default severity 8').

This is demonstrated below.

C2(rw)->router
C2(rw)->router>enable
C2(rw)->router#config
Enter configuration commands:
C2(rw)->router(Config)#license advanced abcdefg123456789
C2(rw)->router(Config)#exit
C2(rw)->router#show license
license advanced abcdefg123456789
C2(rw)->router#exit
C2(rw)->router>exit
C2(rw)->show logging buffer
C2(rw)->set logging application System level 8
C2(rw)->set logging default severity 8
C2(rw)->show logging buffer

The frequency of each message is...

• every 5 minutes, "License Re-evaluate.";
• every 1 minute, "License DB task: update from unit...";
• every 3 minutes, "License DB check".

Further, if a syslog server has been configured to receive any generated "debug" level 8 messaging ('set logging server 1 ip-addr <IP_address> severity 8 state enable'), it will also receive these "License" messages.

Solution
FAD (Functions as Designed).

If you do not want to see these messages, set either the "System" application or default severity no higher than "informational" level 7.
