Your java version is pretty old and does not respect cgroup limits by default. These memory measurements come via the Linux cgroup facility, which is the kernels built-in resource accounting and enforcement mechanism. We can choose our memory settings at runtime by specifying the JAVA_OPTS environment variable: $ docker run -- rm -ti -e JAVA_OPTS= "-Xms50M -Xmx50M" openjdk-java INFO: Initial Memory (xms) : 50mb INFO: Max Memory (xmx) : 48mb Copy This error will happen when we load too much data at once.
