JVM 崩溃并出现分段错误

JVM 崩溃并出现分段错误

我们有一组 tomcat 服务器,刚刚升级到 debian7/openjdk7/tomcat7(全部来自原版 debian)。现在我们在不同的机器上有两个 JVM 崩溃。两台服务器的硬件相同,配置也完全相同(当然除了 IP 地址)

第一次崩溃:

我们之前从未遇到过任何 JVM 崩溃。

我真的不知道从何说起。看起来像是硬件故障?JDK Bug?Tomcat Bug?

最可能的原因是什么?

答案1

我的 RAM 出现了问题。我们在服务器上安装了新的 RAM,现在一切正常。之后我测试了 OracleJDK 和 OpenJDK,没有发现性能或功能上有任何差异。Oracle JDK 唯一缺少的是完整加密。所以从现在起我更喜欢 OpenJDK。
