| Well, this all sounds good, but it doesnt help much. the 
| clients can't have 
| all their own buffer files, because I run them from my home 
| dir, which is 
| NFS mounted in the network, so they use all one buffer file. 
| so I wanted to 
| set them up, with everyone its own checkpoint file.
| i also cant run a perproxy, and this wouldnt also avoid that 
| the work after 
| a few hours for the single machines is lost.
| for better understanding : its a university network, and I am 
| allowed to 
| run the client over night there sometimes, but with my 
| account I have only 
| my (NFS-mounted) home directory available

You *can* have separate buffer files, using the technique someone else
mentioned of separate config files.  As long as you are setting up a
config file per client, set each config file to use a unique checkpoint

Where buffer files are iffy, shared checkpoint files are absolutely not
an option.  The client assumes it owns the checkpoint file, and rewrites
it every time the work in process is saved.  If you are using checkpoint
files, you *must* guarantee that each client is using a separate config

A clean shutdown of a client will result in all work being saved
properly, checkpoint or not.  The checkpoint file is really intended to
protect against unexpected shutdowns.
