The errors happen with the GCC, Intel & PGI compilers, using MVAPICH2 or OpenMPI, so if it's an issue with my software stack, it would have to be deeper than these.

    What file system are you testing on? Is it a network file system
    like NFS, AFS, or SMB?
    That test was added in HDF5 1.10.0 and tests
    single-writer/multiple-readers (SWMR) functionality. Since that is
    a new feature for 1.10.0, the test is not a part of the HDF5 1.8
    release.

Dana -- here's what I get from the "mount" command:

   cmpool on /cm type zfs (rw,relatime,xattr,noacl)

I don't know how robust our filesystem/fileserver is.
I know we're not running out of space.
Thanks,
