Just a heads up on an error I encountered today:
[PID:06956:040 2013.08.23 16:36:22.231 ERROR MonitoringService ] Error while collecting stats
System.InvalidOperationException: The Counter layout for the Category specified is invalid, a counter of the type: AverageCount64, AverageTimer32, CounterMultiTimer, CounterMultiTimerInverse, CounterMultiTimer100Ns, CounterMultiTimer100NsInverse, RawFraction, or SampleFraction has to be immediately followed by any of the base counter types: AverageBase, CounterMultiBase, RawBase or SampleBase.

Most of the web-interface stopped working as a consequence. A restart seems to have fixed the problem. Not a showstopper, but I thought you would like to know…
Was running an import of around 5m events, took roughly 5hours, transferring commit by commit (I guess doing them one stream at the time would have been a lot faster, but I couldn’t figure out how to do that without messing upp global ordering, wich would have made projections listening to multiple streams problematic).
