[static-and-dynamic]
Both static and dynamic port ranges were specified for the
out-of-band (OOB) communication subsystem:
Static ports: %s
Dynamic ports: %s
Only one can be specified. Please choose either static or
dynamic ports and try again.
#
[include-exclude]
Both TCP interface include and exclude lists were specified:
Include: %s
Exclude: %s
Only one of these can be given.
#
[not-parseable]
The specified network is not parseable. Since we cannot determine
your desired intent, we cannot establish a TCP socket for out-of-band
communications and will therefore abort. Please correct the network
specification and retry.
#
[no-included-found]
None of the TCP networks specified to be included for out-of-band communications
could be found:
Value given: %s
Please revise the specification and try again.
#
[excluded-all]
The specified list of networks to be excluded for TCP out-of-band communications
resulted in no networks being available:
Value given: %s
Please revise the specification and try again.
#
[invalid if_inexclude]
WARNING: An invalid value was given for oob_tcp_if_%s. This
value will be ignored.
Local host: %s
Value: %s
Message: %s
#
[authent-fail]
An attempt was made to make a TCP connection between two hosts:
Initiating host: %s
Receiving host: %s
Unfortunately, the connection was refused due to a failure to
authenticate. This is usually caused by a mis-match between
the security domains of the two hosts - e.g., one might be
using Munge while the other is not. This can typically be
resolved by specifying the desired security method. For
example, adding "--mca sec basic" to your command line.
#
[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.
Local host: %s
Errno: %d (%s)
Probable cause: %s
