Miguel Tablado commented on KAFKA-3476: --------------------------------------- Hi there, With latest apache kafka 0.10.2.1, scala 2.12 and IBM JDK 8_64 I have been facing core dumps after starting the engine. I have disabled JIT by adding the parameter "-Xint" to the KAFKA_JVM_PERFORMANCE_OPTS. These are the resulting vars that worked for me: export KAFKA_GC_LOG_OPTS="-Xverbosegclog:$TRACE_DIR/server-gc.log -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps" export KAFKA_JVM_PERFORMANCE_OPTS="-server -Djava.awt.headless=true -Xint" You can find some information about this on: https://www.ibm.com/support/knowledgecenter/SSYKE2_7.0.0/com.ibm.java.win.70.doc/diag/tools/jitpd_disable.html#jitpd_disable > -Xloggc is not recognised by IBM java > -------------------------------------- > > Key: KAFKA-3476 > URL: https://issues.apache.org/jira/browse/KAFKA-3476 > Project: Kafka > Issue Type: Bug > Components: admin, tools > Affects Versions: 0.9.0.0 > Reporter: Khirod Patra > > Getting below error on AIX server. > NOTE : java version is : > ---------------------------------------------------------------------------------- > java version "1.8.0" > Java(TM) SE Runtime Environment (build pap6480-20150129_02) > IBM J9 VM (build 2.8, JRE 1.8.0 AIX ppc64-64 Compressed References > 20150116_231420 (JIT enabled, AOT enabled) > J9VM - R28_Java8_GA_20150116_2030_B231420 > JIT - tr.r14.java_20150109_82886.02 > GC - R28_Java8_GA_20150116_2030_B231420_CMPRSS > J9CL - 20150116_231420) > JCL - 20150123_01 based on Oracle jdk8u31-b12 > Error : > ------------------------------------------------------------------------------- > kafka-run-class.sh -name zookeeper -loggc > org.apache.zookeeper.server.quorum.QuorumPeerMain > ../config/zookeeper.properties > <?xml version="1.0" ?> > <verbosegc xmlns="http://www.ibm.com/j9/verbosegc" > version="R28_Java8_GA_20150116_2030_B231420_CMPRSS"> > JVMJ9VM007E Command-line option unrecognised: > -Xloggc:/home/test_user/containers/kafka_2.11-0.9.0.0/bin/../logs/zookeeper-gc.log > </verbosegc> > Error: Could not create the Java Virtual Machine. > Error: A fatal exception has occurred.
