 I am not sure if this is the same thing, but anyway ... 

 The version 2.0 at some point also got frozen in a similar way during
the step of reading wavefunction files from 'file', if those existed
only on some nodes but not the others.

 For example, if there were 8 nodes running (2 4-way boxes), and one of
them had *.wfc1, *.wfc2, *.wfc3, *.wfc4 on the local temporary space,
and the other node did NOT have *.wfc5-*.wfc8, then the code would get
frozen while trying to read the wavefunctions.

 Perhaps, somehow the nodes get moved around and the *.wfcN files do
not correspond to the earlier order?
