Not all of the "unknown", actually but what's deeper I can deduct from  
what is there.

I cannot say it for certain, bu it looks suspiciously like a race  
condition, possibly related to the kind of filesystem on which the  
wavefunctions directory (outdir, and consequently ~/tmp, per default).
If I had to bet I would say you are using ~/tmp as the default directory,  
and it is a normal NFS share.

Anyway, it is indeed annoying but should be harmless, as long as it only  
happens at the end of the run. I could try and "fix" it now, but it will  
take some time to check for side effects.

best regards
