Kernel Panic

[Christophe DUMONT]

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 !

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.
