Error during writing of fields in massive parallel simulations

I am performing LES simulations on a big cluster using ~1000 cores. In some cases during writing of the fields half of the processor dictionaries get written for time step n and the other half of the processor directories gets written for the time step n+1. This issue becomes apparent when trying to use the stored solutions for restart etc...
-Wall clock time per time steps is ~0.5s.
-Version 1.6 from the git repository from ~Dec 2009
-A lustre file system is used
Some modified settings:
commsType nonBlocking; //scheduled; //blocking;

The Mantis bug reporting should be up and running again. Could you please report any bugs there?
