Hello engineers!
Sorry for my late answer XD.
At the end it was an IOS problem, we contacted to Cisco TAC and they send us a testing IOS version, because also they had problems determining the exactly cause of the bug.
At this time, with this new IOS we have had no problems. Also, they told us that, with a regular upgrade to the next version, in some cases the problem is solved.
Thank you for the support!
Best regards.

One more solution for those who may also encounter this problem... I receieved the exact same error output and all I had to do was to reseat the RAM chips in our 2811 and voila, the problem is solved.

Ken
