This'll be a software bug but without more detail off your router it's impossible to tell what's causing it. I would suggest you open a TAC case and include a "sho tech" output and the error's above and they'll be able to figure out what's going on.

I addressed all details to my reseller.

But at the same time, I found latest release 12.3(7)T1.

I downloaded and tried : all is working !

I am know looking for release notes and explanations or why not new caveats.

anyway, thanks for reply
