Is there a best practices for this, not a Java buff. I was wondering how can I analyze what exactly I need for my topology.
Right now I am getting this, for nimbus with "Xmx768m": when I run my topology, I get Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00007f64041c1000, 262144, 0) failed; error='Cannot allocate memory' (errno=12) Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000100260000, 131072, 0) failed; error='Cannot allocate memory' (errno=12) Running: java -client -Ddaemon.name= -Dstorm.options= -Dstorm.home=/usr/lib/apache/storm/0.10.0 -Dstorm.log.dir= -Djava.library.path= -Dstorm.conf.file= -cp /usr/lib/apache/storm/0.10.0/lib/reflectasm-1.07-shaded.jar:/usr/lib/apache/storm/0.10.0/lib/kryo-2.21.jar:/usr/lib/apache/storm/0.10.0/lib/log4j-api-2.1.jar:/usr/lib/apache/storm/0.10.0/lib/clojure-1.6.0.jar:/usr/lib/apache/storm/0.10.0/lib/slf4j-api-1.7.7.jar:/usr/lib/apache/storm/0.10.0/lib/log4j-slf4j-impl-2.1.jar:/usr/lib/apache/storm/0.10.0/lib/minlog-1.2.jar:/usr/lib/apache/storm/0.10.0/lib/asm-4.0.jar:/usr/lib/apache/storm/0.10.0/lib/hadoop-auth-2.4.0.jar:/usr/lib/apache/storm/0.10.0/lib/log4j-core-2.1.jar:/usr/lib/apache/storm/0.10.0/lib/servlet-api-2.5.jar:/usr/lib/apache/storm/0.10.0/lib/storm-core-0.10.0.jar:/usr/lib/apache/storm/0.10.0/lib/log4j-over-slf4j-1.6.6.jar:/usr/lib/apache/storm/0.10.0/lib/disruptor-2.10.4.jar:sirius-15.4.jar:/usr/lib/apache/storm/0.10.0/conf:/usr/lib/apache/storm/0.10.0/bin -Dstorm.jar=sirius-15.4.jar com.gobalto.sirius.topology.StarSchemaTopology Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00007f1b13654000, 262144, 0) failed; error='Cannot allocate memory' (errno=12)
