JVM 因分段错误而崩溃

  • 772

我们有一个 tomcat 服务器集群，刚刚升级到 debian7/openjdk7/tomcat7（全部来自库存 debian）。现在我们在不同的机器上发生了两次 JVM 崩溃。两台服务器具有相同的硬件并且配置完全相同（当然除了 IP 地址）

第一次崩溃：

我们以前从未发生过任何 JVM 崩溃。

我真的不知道从哪里开始。它看起来像硬件故障吗？JDK错误？雄猫虫？

最可能的原因是什么？

java

    我的 RAM 存在问题。我们在服务器中有新的 RAM，现在一切正常。之后我测试了 OracleJDK 和 OpenJDK，我看不出性能或功能有任何差异。Oracle JDK 中唯一缺少的是完整的密码学。所以从现在开始我更喜欢 OpenJDK。
