Hello,

I'm sorry for the delayed response!  Unfortunately, we don't have access to an 
aix system for testing, so I am unable to duplicate your issue.  I suspect that 
issue is related to how the test is configured; I have seen similar issues on 
other platforms.  These issues have not translated to an error in the library, 
however, so it should be safe to ignore.  The error was with how the test was 
constructed.

As a side note, I would recommend updating your hdf5 to the recently-released 
1.8.14; we saw several issues when running parallel I/O on 1.8.13 that were 
fixed with the most recent release. I don't think that is related to the issue 
you have reported, but it is something else you may encounter.

Sorry again for the delayed response; have a great day!
