bpsh and memory leak - wien

Hi

We try to use WIEN97 on our Scyld beowulf cluster, and 
the following happens : the program lapw1 (more or less
pure fortran 77), run interactively on the front node,
happily grows to, say, 30Mo and then runs until completion.
When run with bpsh on a remote node, the available memory
just shrinks down until the system swaps to stall.
Any ideas ? Is it some kind of weird file access problem with NFS,
wrong caching ? Free -t or meminfo seem to indicate that 
it it just the remote program growing forever.


Thanks in advance for any help
