Exactly, but I could not find any way to prevent this from happening. Even after I disabled switcher globally it was still producing the same Tcl error under SGE. So I had to remove it completely to get rid of it. > switcher sets the proper environment for your user and then your jobs > are run as your user so the environment is correct.

I know it should "just work"... in ones dreams ;-) For instance, I have spent whole day trying to debug another weird problem: I want all of the home directories on the cluster to be NFS-mounted on an external fileserver, not on the master node as in default OSCAR setup. Pretty simple thing, isn't it? I've changed /etc/fstab accordingly, added proper entries to /etc/exports on the server and connect it to the same switch the rest of the cluster using. Restarting netfs worked without errors, no errors on server either, but all filesystems are mounted read-only, that's it. Exportfs on server says they are exported rw, mount on client says the are mounted rw, rpcbind and nfslock services checked Ok, firewall not in the way (and I tried disabling it), rebooted both server and clients to be sure -- nothing helped. Any write access to NFS mounts on clients is denied, no matter what I tried. And you say it should just work...
