IDEA 2016.3.x throws out of memory error immediately after launching

I have been trying to use IDEA 2016.3.x version but not successful for the last one month. Every time I try to launch, I see OutOfMemoryError : Java heap space within 1-2 minutes. I even adjusted Xms and Xmx values in idea64.vmoptions file but still not working. Did anyone face this issue in 2016.3.x version?

idea64.vmoptions config:

-Xms1024m
-Xmx2048m
-XX:ReservedCodeCacheSize=240m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow
-Dawt.useSystemAAFontSettings=lcd
-Dsun.java2d.renderer=sun.java2d.marlin.MarlinRenderingEngine

Terminal error :
ramkumar@VL-RAMKUMARK:/data/ramkumar/IDEs/Intellij/IDEA/idea-IU-163.10154.41/bin$ ./idea.sh
