Error with the decl'HDF5 plugin in parallel

Using the decl'HDF5 along with the MPI plugin, I sometimes get errors like: [14:43:36][MPI 000000][PDI] *** error: Error while triggering event 'dump': System_error: Filename collision data_000000000.h5': Cannot delete old file.

I am using the replace_and_warn policy. It seems to work well when there are no existing files or with other policies.
