[Users] Error to write PittNull during checkpointing

[Jakob Hansen]

Hi,

I'm experimenting a bit with using the PittNull / SphericalHarmonicDecomp
thorn but I've been experiencing a few errors in writing to its output
metric_obs_0_Decomp.h5 file.

On some occations it seems that this output file cannot be opened and hence
leaving gaps in the data file. This always occurs when carpet is doing
checkpoininting.  Everything else runs well, though, and the simulations
finishes fine. However, when trying to fftwfilter the
metric_obs_0_Decomp.h5 file, I notice the missing data points.

I've checked system logs and there seem to be no hardware failure. Also, as
far as I can see, I'm not overusing memory allocation either.

Anyone else experienced similar issues?

Here follows output from error file :
