Mathieu,

I have had a similar issue that you are facing with SSO redundancy between both supervisors. It turned out to be a problem with the backplane. The errors that you posted show that:

There is probably a software failure creating a communication problem between the active supervisor engine and the standby supervisor engine. SSO Redundancy mode cannot operate reliably when this condition occurs.

I would recommend putting in a TAC case and they can determine that it is a hardware issue .

HTH,

Mark
