Description
When Xms is low, off heap usage can grow while the JVM doesn't reach the Xmx value. As we have seen on client instances, when the instance is small, 100% off heap usage is reached quickly. At this point the JVM on one hand and the OS + Java libraries using native memory outside Java heap on the other compete for memory, leading to either of those eventually crashing.
