[netCDF #GLM-296638]: netCDF write failure after a certain number of writes

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

> The attached C program reproduces this failure. I reproduced this with netCDF
> 4.3.2 and 4.3.3-rc2. NetCDF 4.2.0, 4.2.1 and 4.2.1.1 show a similar failure,
> but instead of returning with an error, the calls do not return at all.
