[mpich-discuss] "the supplied buffer contains invalid memory"

[Rajeev Thakur]

No, but it comes from this part in  mpid/common/sock/poll/socki_util.i

    else if (os_errno == EFAULT || os_errno == EINVAL)
    {
        mpi_errno = MPIR_Err_create_code(MPI_SUCCESS, MPIR_ERR_RECOVERABLE, fcname, line, MPIDU_SOCK_ERR_BAD_BUF,
                                         "**sock|badbuf", "**sock|poll|badbuf %d %d %d %s",
                                         pollinfo->sock_set->id, pollinfo->sock_id, os_errno, MPIU_Strerror(os_errno));

Some read or write socket operation earlier returned EFAULT  (Bad address) or EINVAL (Invalid argument)
