Can you please point me to the exact code you're seeing this in?
It seems not to be in https://github.com/openchange/openchange

How is dcerpc_binding_handle_async_call_done() triggered?

dcesrv_cleanup_broken_connections() is really an implementation
detail we want to be hidden and not exposed.

Maybe we need to call it also from dcesrv_sock_report_output_data()?
Which is triggered from dcesrv_reply().
