though I was able to resolve this as a quick-fix by installing a new cq instance,
I still donot know the root cause. This was occuring in OTB Geometrixx application in author instance ..
reading something like " org.apache.jsp.libs.foundation.components.primary.cq.Page.page_jsp" content
not found exception pointing to Page.jsp in foundation/components and Proxy.jsp referenced in Page.jsp.
Has anyone faced this issue and aware of the ' root cause' behind it. (Sorry the logs are gone now)
