[Users] Simulation domain volume and reduction weight sum differ

Hi,

Using mercurial, I get this warning during simulations :

INFO (CarpetReduce): Simulation domain volume: 170368000 INFO (CarpetReduce): Reduction weight sum: 170367999.880642 WARNING level 1 in thorn CarpetReduce processor 0 host tachyon2974 (line 120 of /home01/r632kgw/jakob/CactusP/arrangements/Carpet/CarpetReduce/src/mask_test.c):

-> Simulation domain volume and reduction weight sum differ

Simulations seem to run okay though. What is causing this warning and is it serious or can I just ignore it?

Cheers, Jakob
