Hello Dominik,

Thank you very much for providing this test file; it will be very useful.  We 
have had intermittent reports of this (or a similar) issue but it has been very 
hard to duplicate.  

We are mostly out of the office this week due to a Holiday, but I will be 
following up on this the best that I can until then.  Please don't worry if you 
haven't heard back from us before next week.

If I might ask, which version of linux are you using, and which MPI libraries 
are yo uusing (openmpi, mpich)?  I'll be testing this in a virtual environment, 
and would like to replicate your system as closely as possible.

Thanks once again, this will be very useful!  Have a good day,

-Ward

> NetCDF: Error initializing for parallel access
> This happens with put_var1 as well as with put_varm with stride > 1. put_vara

> The attached C program reproduces this failure. I reproduced this with netCDF

> but instead of returning with an error, the calls do not return at all.
