Hi, We have been trying to use TrackReco in hep.lcd 0.98, but we haven't got very far. Anytime we try to do anything with track reconstruction, we get an OutOfMemoryError. I was wondering if anyone else is able to reproduce this? It is crimping our ability to do analysis at the moment (we have gone back to 0.97 without track fitting for the moment). Here's a simple 3-line program that causes this error for us: public class TrackTest extends hep.lcd.util.driver.Driver { public TrackTest () { add (new hep.lcd.recon.tracking.TrackReco()); } } Perhaps this is a Digital Unix thing, although I don't see any obvious problems (the "java" process seems to be taking only about 40MB of memory, although my process limits are set to 120MB of real memory and 1GB of virtual memory). Has anyone seen this problem, or know how to get things working? Thanks! -David Wagner
