Re: [Engine-devel] Fixed -Xmx could kill your JVM

The problem is that were running the JVM with the "-Xms option twice, like this: java -Xms1g -Xms1g ... That doesn't correctly limit the max amount of heap space. It has been fixed in a recent commit [1], so with the updated code the engine will run by default like this: java -Xms1g -Xmx1g ... With this change you could start to see OutOfMemory errors if your engine was using a lot of memory, if you are running stress tests, for example. In that case remember that you can adjust this changing the ENGINE_HEAP_MIN and ENGINE_HEAP_MAX parameters in /etc/sysconfig/ovirt-engine. For example, to use 2g instead of the default of 1g: ENGINE_HEAP_MIN=2g ENGINE_HEAP_MAX=2g The restart the engine. Let me know if you have issues.
