> It sounds like you might be calling bm_request_event() when starting a run, but not calling bm_delete_request() when the run stops. So you end up "leaking" event requests and eventually reach the limit of 10 open requests.

> In examples/eventbuilder/mevb.c the request deletion happens in source_unbooking(), which is called as part of the "run stopping" logic. I've just updated the midas repository so the example compiles correctly, and was able to start/stop 15 runs without crashing.
