Today we had packet loss in our datacenter Nedzone Steenbergen.

After investigation we have noticed a hardware defect in one of the linecards.
The card was only using limited memory space for the routes installed (1M vs 2M).

The issue was not clear at first as everything was looking correctly including optical values. After further investigation we see that the card is not functioning correctly because of the above reason and have currently disabled the ports affected until we have a fix at hand.
