Description
By default, the JVM will use up to 25% of total system memory for its heap space. Normally this is not an issue since candlepin stays below that amount, but there are situations where it can use quite a bit of memory.
Without the Xmx setting for JAVA_OPTS in tomcat.conf, the JVM does not know that it should cap its heap space usage for system stability purposes. Eventually, this will lead to OOMs.
Ideally, this can be something configurable via the installer, with a default of 6GB. Note that this is just a cap, it won't use 6GB on startup.
