Hello, 

We downgraded to older kernel. We still facing the same Kernel Panic with different Kernel.

That just tells you that the currently executing process was java. 

It says nothing at all about a memory leak, and as I already mentioned, if Java 
was leaking memory, it would almost certainly have been leaking memory on a 
previous kernel. 

The important part almost always isn't the running process, it's the kernel 
stack traceback, which in this case has 'futex' scribbled *all* over it. 

General rule of thumb: 

If you get more than one crash that has a similar traceback that points at a 
specific syscall, or file system driver, etc, the bug is almost guaranteed to 
be in that code. 

If you get a rash of crashes with *different* tracebacks, you probably have 
some other code that's overlaying memory.
