I'll see if I can find out where that is today, but if you see the same thing as above, do you have any ideas?
I was seeing crashes happen all over the place. It seems like memory is getting corrupted by the call to the Metrics::reset function. If you comment out that one function (in base/frameworks/metrics/non-cluster.bro) the crashes should also stop but the metrics framework also doesn't work correctly anymore! We do probably need to find an open tracefile soon that exhibits these corruption crashes.
