[rds-devel] FW: RDS -- how to detect peer is gone ?

[Tang, Changqing]

Tina,
        It was my mistake. 32bit application works on 64bit kernel.

        The mistake was that I use 'struct iovec' for rds_rdma_args.local_vec_addr,
It should be 'struct rds_iovec'; the reason that 64bit works is that "struct iovec" and
"struct rds_iovec" are the same size, in 32bit, they are different.

        Thanks for help.

    Because you are using a 64b interface with a 32b application.
    Try 32b unmodified.
