this issue has a working solution now. Mainly this is a bug with Linux NFS. When the executable or jar which is open by some process, gets overwritten, it fails at one server as txt is open in memory. But file gets written. So one server has correct while other server not. We r working with Linux on this..
I am mainly thankful to Jeff Lightner, he pointed towards flock, but that is not the case as it is simple ssh copy...
Thanks and regards

Is the nfs export mounted as rw on both hosts?? That
should never be done.
Check it.
