WARNING: An invalid value was given for the btl_tcp_port_min_%s. Legal

(reset to the default value of 1024).

[client connect fail]
WARNING: Open MPI failed to TCP connect to a peer MPI process. This
should not happen.
Your Open MPI job may now fail.

#
[client handshake fail]
WARNING: Open MPI failed to handshake with a connecting peer MPI
process over TCP. This should not happen.
Your Open MPI job may now fail.
Local host: %s
PID: %d
Message: %s
#
[accept failed]
WARNING: The accept(3) system call failed on a TCP socket. While this
should generally never happen on a well-configured HPC system, the
most common causes when it does occur are:
* The process ran out of file descriptors
* The operating system ran out of file descriptors
* The operating system ran out of memory
Your Open MPI job will likely hang until the failure resason is fixed
(e.g., more file descriptors and/or memory becomes available), and may
eventually timeout / abort.
