Well, what made you think "Java memory leak"?

Java is userspace.  If it's leaking memory so far that the kernel has problems, it would probably:

a) Have been leaking memory and causing problems in -957 as well
b) Died in the OOM (Out Of Memory) code, rather than in the futex() system call.

Yes, poorly written Java code will leak memory like a sieve, but this doesn't smell
anything remotely like a memory leak.

I agree with Valentin that it's probably the bug report he references.
