Hi
my application was built using the com.ibm.etools version of GEF and
draw2d, lately, i found out that when the graph tends to include a lot of
nodes and connections, sometimes i get the following exception:
org.eclipse.swt.SWTError: No more handles

has another idea how to reduce the number of OS handles, please let me know
thanks

This stack trace is coming in through the repairDamage(..) method, not the
OverviewWindow. The fix in 2.0.1 was to do a tiled update of the Overview
window to avoid requiring a really large Image.
Most likely, you have a resource leak and have run out of OS handles for
Images. Draw2d needs to new an Image during paint, but it disposes it later.
There is an SWT utility to track down resource leaks. Check the SWT
homepage.
