JVM Crash: scavenge_contents_parallel

I have a JVM with 1.8TB of heap space. Starting from last night, it crashes every couple of hours on:

[GC (GCLocker Initiated GC)

A fatal error has been detected by the Java Runtime Environment:

Java VM: Java HotSpot(TM) 64-Bit Server VM (25.101-b13 mixed mode linux-amd64)

Problematic frame:

CardTableExtension::scavenge_contents_parallel(ObjectStartArray*, MutableSpace*, HeapWord*, PSPromotionManager*, unsigned int, unsigned int)+0xbf3

Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

An error report file with more information is saved as: See file here

Anyone encountered that and knows what's causing it?
