[GSD] - Exception on analysis

[chepseskaf]

GSD can't process my project, there is an exeption:

Exception in thread "main" java.io.FileNotFoundException: /app/Bureau/
workspace.graphml (Too many open files)
at java.io.FileOutputStream.open(Native Method)
at java.io.FileOutputStream.<init>(FileOutputStream.java:179)
at java.io.FileOutputStream.<init>(FileOutputStream.java:70)
at java.io.FileWriter.<init>(FileWriter.java:46)
at org.google.singletondetector.Main.<init>(Unknown Source)
at org.google.singletondetector.Main.main(Unknown Source)

I'm using this command argument:
java -jar gsd.jar -vbS /app/workspaces/workspace /app/Bureau/
workspace.graphml org.goinfre

Have you got an idea how to work around ?
