CAT4506 %HSRP-5-STATECHANGE Log repeated

[djkim03]

This device(HSRP STB) encountered an unknown Log. 

Mar 21 15:05:55: %HSRP-5-STATECHANGE: Vlan100 Grp 100 state Standby -> Active
Mar 21 15:06:23: %HSRP-5-STATECHANGE: Vlan100 Grp 100 state Active -> Speak
Mar 21 15:06:26: %HSRP-5-STATECHANGE: Vlan100 Grp 100 state Speak -> Standby

Log occurs repeatedly, and no log occurs on the active device.
I don't know the cause, but is there a similar case?
