我们一共16个服务接入cat,启动时数据全部正常,但是运行一段时间后,大概2周左右,就会出现一次客户端数据丢失。重启cat后立马恢复正常,请问有什么排查思路吗
单节点部署,参数如下: CATALINA_OPTS="$CATALINA_OPTS -server -Djava.awt.headless=true -Xms15G -Xmx15G -XX:PermSize=256m -XX:MaxPermSize=256m -XX:NewSize=10144m -XX:MaxNewSize=10144m -XX:SurvivorRatio=10 -XX:+UseParNewGC -XX:ParallelGCThreads=4 -XX:MaxTenuringThreshold=13 -XX:+UseConcMarkSweepGC -XX:+DisableExplicitGC -XX:+UseCMSInitiatingOccupancyOnly -XX:+ScavengeBeforeFullGC -XX:+UseCMSCompactAtFullCollection -XX:+CMSParallelRemarkEnabled -XX:CMSFullGCsBeforeCompaction=9 -XX:CMSInitiatingOccupancyFraction=60 -XX:+CMSClassUnloadingEnabled -XX:SoftRefLRUPolicyMSPerMB=0 -XX:-ReduceInitialCardMarks -XX:+CMSPermGenSweepingEnabled -XX:CMSInitiatingPermOccupancyFraction=70 -XX:+ExplicitGCInvokesConcurrent -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.EPollSelectorProvider -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCApplicationConcurrentTime -XX:+PrintHeapAtGC -Xloggc:/data/applogs/heap_trace.txt -XX:-HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/data/applogs/HeapDumpOnOutOfMemoryError -Djava.util.Arrays.useLegacyMergeSort=true"
我也遇到了,请问是否表现为,服务运行一段时间,突然在一个时间点心跳等报表信息都没有了,重启服务或者重启上报的cat节点会重新恢复
我的也是
