Have you looked at the software you are using for the BGP peerings.
And the machine you are using to run that sw on.

0-4% packet can hardly account for a session loss based on TCP.
If pings to the guest net are not affected then the common elements
of the router can hardly be the problem. If there is one it must be
either traffic patterns or cards, as you say Monica suspects.

Why before? I think the AMS-IX upgrade shouldn't be interfered by
this. Even it happens to be a problem with the fast ethernet card in
marken, it can only provides us more data and if we have to move the
connection to a 10Mbit/s ethernet while the card is replaced, then we
are no worse than now.
