I am enclosing a gzip'd form of his email which should make it through.

I think it is an SGID of 0 in the PathRecord request.

The error message in the log came from osm/opensm/osm_sa_path_record.c:

static ib_net16_t
__osm_pr_rcv_get_end_points(
...
    if( *pp_src_port == (osm_port_t*)cl_qmap_end(
          &p_rcv->p_subn->port_guid_tbl ) )
    {
      /*
        This 'error' is the client's fault (bad gid) so
        don't enter it as an error in our own log.
        Return an error response to the client.
      */
      osm_log( p_rcv->p_log, OSM_LOG_VERBOSE,
               "__osm_pr_rcv_get_end_points: "
               "No source port with GUID = 0x%016" PRIx64 ".\n",
               cl_ntoh64( p_pr->sgid.unicast.interface_id) );
  
      sa_status = IB_SA_MAD_STATUS_INVALID_GID;
      goto Exit;
