更新：我安装了Oracle版本的jdk1.7，并使用update-alternative来使用Oracle jdk而不是openjdk，然后问题就消失了。我的一些frds说openJDK有时会有bug。不知道为什么，但无论如何它已经解决了。
大家好我是linux的新手，但最近我租了一个网络托管服务器来测试我自己的项目。（os：ubuntu 12.04，它预装了Tomcat7，mysql，nginx和jdk7）
有趣的事情发生在昨天我将一个webapp部署到tomcat之后。 hs_err_pidxxxxx.log每隔一小时就会生成一次。以下是生成的相关错误日志的屏幕截图：

所以你看到每小时第6分钟生成的所有文件？我发现了这个，并尝试在May28 13:37重启我的机器，tomcat与系统一起自动重启，然后错误文件开始每隔37分钟生成一次。起初我没有意识到这个原因，直到我关闭tomcat服务器，然后错误日志消失了！
这些错误日志真的很烦人，当Tomcat打开时，消耗的内存java也非常高。以下是运行命令ps aux --sort rss

我还从tomcat中删除了我部署的webapp，但仍然出现了错误日志...... 真的需要一些帮助或暗示我应该怎么处理这个错误文件，我读了一些参考文档，但没有太多的想法。
这是hs_err_pidxxxxx.log，都非常类似于

答案 0 :(得分：1)
这次崩溃的原因是JVM无法从操作系统获得所需的内存。例如，如果您的计算机本身具有8 GB RAM，并且将-Xmx配置为12GB，则JVM将在您创建新对象时尝试请求此内存。
在那个时候，如果JVM无法获得足够的内存，它就会像这样崩溃。
答案 1 :(得分：0)
你确定Tomcat实际上是在使用64位的Java 7 JVM吗？ JVM崩溃转储（即调用hs_err_*个文件）表示：There is insufficient memory for the Java Runtime Environment to continue.和In 32 bit mode, the process size limit was hit。当JVM（本机代码）或链接库执行非法操作时，将生成故障转储。当tomcat正在运行时，请确保您可以使用jps命令监视JVM。如果JVM以32位模式运行，那么它只能访问堆上大约3.5GB的内存（即使有大量可用的虚拟内存 - 这是您可以/应该使用64位JVM的地方）。 / p>
崩溃转储看起来有点奇怪。转储主要意味着内部JVM /库错误。但我很困惑，你正在做的事情就是造成这种情况。根据我的经验，它曾用于显示遇到操作系统违规的有问题的框架。在您的转储中，查看是否存在有问题的框架。
另一件事是在JVM看到OOMError时实际转储Java线程。这通常是通过在JAVA_OPTS /etc/default/tomcat7中添加一个新选项-XX:+HeapDumpOnOutOfMemoryError来完成的，这样您就可以了解当JVM进入{{1}时Java /本机线程实际在做什么}}
