Re: [ZOOKEEPER] - Error - HEAP MEMORY
Hi, My environment have 5 servers with solr + zookeeper in the same hosts. However, I've had 48 RAM each servers (solr - xms 28 gb and xmx - 32 gb). Looking for my servers and process, in zookeepers has xmx 1000 mb and xmx 4096 mb (last item, was change for me). Why 2 values for xmx?

Re: [ZOOKEEPER] - Error - HEAP MEMORY
Hi, I don’t find any documentation about the parameter zookeeper_server_java_heaps in zoo.cfg. The way to control java heap size is either the java.env file of the zookeeper-env.sh file. In zookeeper-env.sh SERVER_JVMFLAGS="-Xmx=512m" How many RAM on your server ?
