Hi, This is a known limitation of the babeltrace 1 python bindings, you'll have to either deep copy the events you want to do further processing on or iterate multiple times on the trace collection. This limitation will be fixed in the bt2 bindings and you'll be able to keep references to events. Regards, Michael
