Hi Wolfgang,

You have hit the system or shell file handles limit. Look at this search 
for explanations and solutions about the problem:

http://www.google.com/search?client=ubuntu&channel=fs&q=linux+Too+many+open+files&ie=utf-8&oe=utf-8

This is related to the system, as the number of files (including sockets 
and other system handles) is limited globaly or per user. But it may be 
a gvsig problem if files or remote connections are not closed when not 
used anymore, or remain opened when not really needed.

- Let me ask you some questions to try to know how how reached the 
opened files limit:

- Do you have a gvsig project with a lot (I mean hundreds if not 
thousands) of layers? Or many gvsig instances?

- Are you using other programs at the same time as gvsig?

- Could you send us how many files opened has the gvsig process? To 
obtain it, for example in gnome, open the system monitor , right-click 
on the gvSIG java process and select the "show open files" menu option 
(it may take a while).
