[ofa-general] Help - RDMA event files remain open after acknowledging them

The following calls result in opening files to the kernel:

ibv_create_comp_channel() - used to report cq events
rdma_create_event_channel() - used to report rdma cm events

Be sure that there are corresponding calls to:

ibv_destroy_comp_channel()
rdma_destroy_event_channel()

These are the calls that close the opened files.
