will do. Another data point.. I've had the same image (3715) on our
testbed for almost 2 days with no core dumps. Differences between the
testbed and our "real" network: only 1 gateway, only 4 nodes, essentially
no traffic, and all the nodes are using the same revision. Can I make a
valid test of new software by only upgrading a single gateway on our
network, or do I need to upgrade the other nodes visible to the gateway
too?
