我每隔几天就在java 1.6.0_07上运行Tomcat 6.0.16时遇到以下jvm崩溃。
效果是tomcat立即死亡。
这意味着什么？

它基本上与JVM代码中的segfault崩溃。 ExceptionCode = 0xc0000005表示段错误。 JVM线程（tid = 0x4ca02000）尝试写入ECX = 0x616c632e寄存器指向的地址，该寄存器看起来不可访问，并导致段错误。我可以看到基于所提供信息的两个原因，或者是由于访问垃圾收集导致的对象损坏问题或者在Java堆中的压缩（可能是perm区域 - 只是基于堆统计中显示的占用率的猜测）或者可能是由于JIT编译的代码导致对象损坏。首先有点难以弄清楚，因为它需要系统转储分析，但看起来第二个很容易通过使用-Xint选项禁用JIT来检查。你可以尝试这个，如果它解决了问题可能是JIT做得不好。如果最近在JIT中修复了某些内容并且可以升级到最新版本，你可以查看最新版本。
答案 1 :(得分：1)
我会尝试将JVM升级到最新版本。从那时起，已经有很多修复。
答案 2 :(得分：0)
在我的情况下，这是一次内存崩溃。修复了将此参数添加到JVM启动配置：-Xmx512M
