Hi all,
When ever i am trying to acces some tabs in filerview it crashes saying 
HTTP/1.1 500 Internal server error content-type: text/html 
Oops! Had a problem with that Servlet
 500 Internal server error 
java.lang.OutOfMemoryError
but all the other tabs like aggregate,storage,snap mirror are working..
volume,qtree,snapshot,quota,show status are the tabs which gives the error.
ontap version running is 7.3.6
some times i get this error too..
java.lang.OutOfMemoryError
