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.
