我有一个Solr从属实例的内存问题。
问题在于，每当从设备从主设备复制新的更改时，从设备启动一个新的search器，显然旧设备不会被释放。
最终，年轻的collections品已经满了，并且已经stream入了旧的collections品（或者至less是它的样子），并且开始不断地进行完整的垃圾收集。 现在看起来实际上并没有能够释放任何明显的记忆。 完整的垃圾收集可能会导致通常需要几毫秒才能执行的search，每10秒就会花费大约1/2到4秒的时间。
再说一次，即使是老一代也是饱满的，然后要么停止一切，要么释放一些记忆，要么就是完全locking，显然永远不能回到function。
一些系统信息：
该机器是Amazon AWS m1.medium机器：
3.7GB memory
20GB HDD space
1 CPU core
2 ECU (1 ECU is the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor).
操作系统：Ubuntu 12.10
Java：
java version "1.7.0_09"
OpenJDK Runtime Environment (IcedTea7 2.3.3) (7u9-2.3.3-0ubuntu1~12.10.1)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)
Java servlet：Tomcat 7
Solr：4.0
Tomcat启动参数：
-Djava.io.tmpdir=/tmp/tomcat7-tomcat7-tmp -Dcatalina.home=/usr/share/tomcat7 -Dcatalina.base=/var/lib/tomcat7 -Djava.endorsed.dirs=/usr/share/tomcat7/endorsed -javaagent:/spm/spm-monitor/lib/spm-monitor-solr-1.8.0-withdeps.jar=/spm/spm-monitor/conf/spm-monitor-config-[snip]-default.xml -Dcom.sun.management.jmxremote -Xloggc:/var/log/tomcat7/GCLog.txt -XX:+PrintGCDetails -XX:NewSize=500M -Xmx3G -Xms3G -Dsolr.solr.home=/data/solr -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -XX:+UseConcMarkSweepGC -Xmx128m -Djava.awt.headless=true -Djava.util.logging.config.file=/var/lib/tomcat7/conf/logging.properties
spm-monitor是SemaText的监控系统。
Solr有4个核心，4个国家各一个，包含产品信息。 其中3个核心文件数量较less，而第四个核心文件大约有4.7万个文件。 该核心指数目前占用843MB。
这是我的solrconfig.xml： http : //pastebin.com/c5vHKgMF
和我的schema.xml： http : //pastebin.com/tFA4bmT5
我使用pastebin，否则这个post太大了。
以下是jstat -gc [pid] 2s的输出如何查找各种事件：
当solr启动时，它运行良好，所有查询都花费正常的时间：

我也有一堆从它停止了甚至能够回应search，所以如果有人希望从我可以提供一些输出的jhat 。
有没有人有任何想法为什么solr / tomcat / java这样做？ 我可以一贯地复制它，所以如果你需要更多的debugging信息，我也可以提供。
-Xmx3G
-Xms3G
-Dsolr.solr.home = /数据/ solr的
-Djava.util.logging.manager = org.apache.juli.ClassLoaderLogManager
-XX：+ UseConcMarkSweepGC
-Xmx128m
为什么你有两个最大堆设置？ 这是一个复制粘贴错误？ 或者是你的tomcatconfiguration的方式？ 另请看看你是否可以减less到512M或1G的最小堆。 一般不鼓励同样大小的最小和最大的堆。
