load "java.lang.OutOfMemoryError"

The Ghost of "Out of memory" is driving me crazy now. I switched to command line of RTC from RTC Eclipse plugin in anticipation of getting rid of this issue. But Still with the lscm I am seeing this issue. I have bumped up the "max heap" as -
cat scm.ini
-vm
../../client/eclipse/jdk/jre/bin
--launcher.suppressErrors
-data
@noDefault
-vmargs
-Xmx12512m
-Xshareclasses:nonfatal
-Xquickstart
-Dosgi.requiredJavaVersion=1.5

What else I can do to overcome this issue. This is particular to my system only and none in my team is facing this issue. They are okay with the default ini. So I doubt if this is really the issue. Kindly help me to resolve this..
