| I think that is an error; it looks like the rendering process is leaving files "open". I have a hard time to believe it (given the stability of geoserver), I will try and reproduce here.
Can I just quickly ask what platform you are on? I would like to reproduce this before pestering aaime. Also note that if moovida can cut you a copy of trunk the shapefile renderer will probably not have this issue.
I will be issuing a 1.2-SNAPSHOT in three hours, gathering up the fixes over the last couple of days.

Hi all,
I was using uDig and have a problem in this situation:
1. have 9 shapefile loaded in the Layers view
2. have 1 ecw loaded in the Layers view
3. did an intersect operation with Axios
4. did an other Clip operation with Axios
5. got the following error while rendering... too many open files.
What do you think about it?
