Hi, I've downloaded the latest version of librdma_cm 1.0.12.
I got unexpected segfault (hum, usually segfault is not really expected .. ;) On the same server I execute the rdma_server and rdma_client. The first is waiting incoming message. The second one segfault. This is the backtrace of the rdma_client: #0 0x00007f3de011482d in ?? () from /usr/lib/libmlx4-rdmav2.so #1 0x00007f3de011640e in ??
