So far we have been unable to find a reproducer. While i've managed to have problems with individual machines, that seem to fail at some random point of their own choosing, the most reliable way to produce problem for us to have a number of nodes updating various RRD files frequently. Given that i haven't found a reliable and short method for reproducing it either, if we were to re-run the known case and capture all network traffic, would you be able to extract the relevant detail to generate a simulation?
