Operating System - Unspecified / All
Severity - Low

Reported Version - 1.2
Due in Version - Undecided
Due Date - Undecided
Details - Triggered e.g. with "dnaplfv 4 1 30" in pdelab-howto (-r 532) when using AMG with 32 processes.

It seems like it happens somewhere in fillIndexSetHoles. Further investigation is needed but currently time is lacking.

Meanwhile the bug is circumvented by setting up complete index sets (one index for every unknown).
