Error with plotting during simulation

Simulations sometimes crash when trying to plot the results from outputs while the simulation is still running. I get the following error:

Traceback (most recent call last):

--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 0.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------

Times at which this occurs corresponds times when I tried to simultaneously use output functions that load results from the output files, such as:

output.spatial_means.plot()
output.spectra.plot1d()
output.spectra.plot_kzkh()

The output works fine, but it seems to make the simulation crash when it takes too long (a lot of data to load from files).
