Hello, What made me think about a memory leak is the message : Java Not Tainted 3.10.0-1062.1.1.el7.x86_64. I can’t access the bug report referenced : an active redhat subscription is needed !

We're facing Kernel Panic on CentOS 7 since upgrading from 3.10.0-957 to 3.10.0-1062. I'm thinking about a java memory leak, but not sure.
Do you know what's going on here ?
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.
