I looked at this over the weekend and still don't have a working theory. req_comp_work calls req_free which based on the pend->type frees the (in this case) path request (calls free_path_req). It is the same as the one which was allocated from the path request cache in ib_at_paths_by_route. We are still looking at this. -- Hal > > james > > On Sat, 7 May 2005, Tom Duffy wrote: > > > On Sat, 2005-05-07 at 01:54 -0400, Hal Rosenstock wrote: > >> Is the client connecting to a server which is present or not ? > > > > Yes, the client *is* connecting to the server.
