Unable to build the workspace

I am using eclipse Kepler with plugins JBOSS(wildfly-8.2.0.Final) and ClearCase, while building the workspace i am getting the following error "ENTRY org.eclipse.core.jobs 4 2 2016-06-02 11:07:19.724
!MESSAGE An internal error occurred during: "Building workspace".
!STACK 0
java.lang.StackOverflowError"

Attached logs.

We have tried the following solutions:
1. We tried increasing the memory size in eclipse.ini file as below but it doesn't seems to work:

--launcher.XXMaxPermSize
1024M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
1024m
--launcher.appendVmargs
-vm "C:\Program Files\Java\jre7"
-Dosgi.requiredJavaVersion=1.7
-Xms2048m
-Xmx2048m

2. When the RAM was checked using task manager eclipse was taking 365MB of memory.

Please guide us some other workaround to resolve the issue.

thanks,
Megha
