[e-nsp] EAPS - Fail-timer-exp flag set. Domain state: Complete

[Dudek, Michael]

No matter whether it is XOS Version 12.4.1.7 v1241b7-patch1-7 nor
EW-Version 7.8e.2.1, at a certain time, mainly between 12.00 to 01.00 pm
I get  hundreds of messages in the syslogs like

09/27/2010 12:47:32.81 <Info:EAPS.DmnInfo> EAPSD DSK33 - Fail-timer-exp
flag cleared. Domain state: Complete

There are nearly all EAPS-Master from 24 EAPS-Rings affected. My
investigations shows the following:

All the eaps-rings have no configuration errors. 
There are no rx- or tx-errors on the uplinks. 
Network performance is not affected. 
It must be a certain vlan from which the interference comes, this vlan
is known. 
It happens only on weekdays and during office hours 
I have no details found with wireshark, but I'm not an expert with
wireshark 
I found some references about IPv6 neighbor discovery protocol, there
are some W7 PCs in that vlan. 

My guess is that something teases the cpu of the eaps-masters but how
can I catch that thing?
Does anyone have a suggestion how I can get this under control with EW
or XOS or wireshark or anything else?

Thanks a lot, Mikeld
