**** Configuraion ****

is_server = true msg_size = 64 num_concurr_msgs = 1 sock_port = 8080

**** End of Configuraion ****

Getting the same issue. Need to reduce max_send_wr & max_recv_wr in struct qp_init_attr

I get the same issue, too. I've tried reduce max_send_wr & max_recv_wr in struct qp_init_attr, but it doesn't work.
