Tomcat自动关闭问题,求教如何分析错误日志!!!

tomcat运行一段时间后会自动关闭,并产生错误日志,怀疑是客户端访问同时读取大字段造成的问题,但是看不懂错误日志文档,求教如何分析问题,错误日志见附件 :cry: :cry:

4个回答

从日志看是调本地库的时候引起jvm崩溃的。
本地库是spring jdbc调的。
从你的heap信息看,perm区已经满了。
你设置了-XX:MaxPermSize=512m,但是初始时只分了64M
你改成-XX:PermSize=512m -XX:MaxPermSize=512m试试吧。
另外看你们的系统日志,客户端和服务端这个时候做了什么,是不是有些异常操作,或者大数据量的不合理操作。

com.ztkj.emr.application.mz.server.dao.jdbc.impl.EMRApplicationMzTemplateDaoJdbcImpl$PagetempletMapper.mapRow(Ljava/sql/ResultSet;I)Ljava/lang/Object;+43
看岔了,是这个调的本地库,获取lob字段时需要调用oracle的本地库。

你用了spring,spring会生成大量类文件,XX:PermSize可以设置的大点

从日志上看是从oracle读取xml文件产生的问题,这个地方是什么情况,可以具体的说明一下

ps:监控产生异常时oracle的情况

tomcat自动关闭的问题

现状:在一台windows服务器(阿里的ECS)上 放了两个tomcat和一个bat执行的Jar。 出现问题:会偶发性的tomcat自动关闭。 这是hs_err_pid.log文件中开头的内容 # There is insufficient memory for the Java Runtime Environment to continue. # Native memory allocation (malloc) failed to allocate 32744 bytes for ChunkPool::allocate 根据网上设置Tomcat启动的初始内存,有的会出现起不来,有的设置了还是会有tomcat自动关闭的情况。 如何解决这个问题比较好,如果还是设置tomcat启动内存,那该如何设置比较好。可能我网上看的设置方式有问题。

Tomcat运行一段时间后自动退出

最近tomcat运行一个项目,运行一两天就自动关闭,也没有报错。 以下是网上查找别人说的原因: 1,并发用户数目过大,也会导致tomcat自动停止服务。 2,系统本身的网络负载平衡没有做好,导致tomcat自动停止服务; 3,程序迭代不合理也是一个原因; 4,数据库连接未关闭,导致资源损耗过重,会引起服务停止; 5,程序严重错误,也会引起tomcat停止服务! 想请问以下,除以上外,还有什么原因会引起tomcat自动关闭。有什么软件可以测试或者模拟异常之类?
