完整GC期间JVM崩溃

时间：2012-11-12 09:48:58

标签： jvm-crash

我正在使用JDK1.5运行应用程序，并且在完整的gc运行期间，JVM崩溃和应用程序终止。我试图找到答案并搜索所有博客，但无济于事。请帮助解决这个问题。

以下是我对JVM的配置。

$JAVA -server -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=55555 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Xms200m -Xmx200m -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -Xloggc:/tmp/gc.log -cp $CLASSPATH org.jpos.q2.Q2 $* -d $DEPLOYDIR

以下是gc.log的最后一部分，直到它在完整GC期间终止。

看起来像是内存泄漏的可能迹象。我建议自动添加HeapDump

-XX：+ HeapDumpOnOutOfMemoryError

切换到Java参数。并通过各种工具运行，如VisualVM或Eclipse Memory Analyzer
