[Wien] I/O buffer

[Peter Blaha]

It is a problem of the machine. Most likely  NFS or a possible harddisk 
failure.

Check your NFS, put longer "sleep" times in lapw1/2para. 
Make a check:
after lapw0 in run_lapw put a   cp case.vns case.vns_save   line
When the crash occurs in vns, compare the two files.
