VRRP state transition traps

[nortelneo]

I am getting the following errors one one of my ERS 8600 switches. It is one of two switches connected together in a VRRP.
I get these errors occasionally. Does anyone know what could be causing it? The network remains stable and no other issues are seen.

Here's a good summary of the messages:

There has been talk of high CPU loads causing problems with VRRP, if that's not the case in your situation you might glance at this previous thread that included discussion that may be helpful:

Hi anthony,
We do not have enough activity for high cpu loads..thanks for the links, i'll keep monitoring...
