multicast data can not receive

On HP-UX, we want to exchange data via multicast, there happen to meet a problem: sometimes the receiver that has joined the group can not receive the multicast data, but the recvfrom call returned no error. We have reconfig the network and added the default the route, but still can not fixed it, anyone can give some idea or some tips on HP-UX multicast programming?

IBV_ATTACH_MCAST(3)					  Libibverbs Programmer's Manual				       IBV_ATTACH_MCAST(3)

NAME
ibv_attach_mcast, ibv_detach_mcast - attach and detach a queue pair (QPs) to/from a multicast group SYNOPSIS
#include <infiniband/verbs.h> int ibv_attach_mcast(struct ibv_qp *qp, const union ibv_gid *gid, uint16_t lid); int ibv_detach_mcast(struct ibv_qp *qp, const union ibv_gid *gid, uint16_t lid); DESCRIPTION
ibv_attach_mcast() attaches the QP qp to the multicast group having MGID gid and MLID lid. ibv_detach_mcast() detaches the QP qp to the multicast group having MGID gid and MLID lid. RETURN VALUE
ibv_attach_mcast() and ibv_detach_mcast() returns 0 on success, or the value of errno on failure (which indicates the failure reason). NOTES
Only QPs of Transport Service Type IBV_QPT_UD may be attached to multicast groups. If a QP is attached to the same multicast group multiple times, the QP will still receive a single copy of a multicast message. In order to receive multicast messages, a join request for the multicast group must be sent to the subnet administrator (SA), so that the fabric's multicast routing is configured to deliver messages to the local port.
