[IGSTK-Users] State Machine Validation Failure

[charles.garraud at irisa.fr]

Hi,

I encounter some memory failure problems when trying to use the 
run-simulator app.

The app runs on a 2GB memory laptop.
The OS is Ubuntu 9.04.
The problem occurs when running some of the igstk examples (it seems to 
be linked to the number of events defined in the events files). For example,
    *igstkDummyTracker.xml with sendEvent files 
igstkDummyTracker_edgecoverage_test_basispath1.xml and 
igstkDummyTracker_nodecoverage_test1.xml
    *igstkLandmark3DRegistration.xml with sendEvent files 
igstkLandmark3DRegistration_edgecoverage_test_basispath1.xml and 
igstkLandmark3DRegistration_nodecoverage_test1.xml

The problem is related to heap memory management (as described here: 
http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html). 
The recursive insertion of element
in igstkvtMergeList.java seems to cause the failure.

Here is the error returned:

java.lang.OutOfMemoryError: GC overhead limit exceeded

I tried to increase the JVM memory capacity (export ANT_OPTS="-Xms1024m 
-Xmx1024m"). It didn't work.

I tried to switch off gc overhead limit (-XX:-UseGCOverheadLimit), but 
(as I expected) it didn't work but just change the error to a heap space 
error:
