正在尝试理解tomcat hs_err_pid日志

Question

下面的hs_err_pid.log是在我的JVM崩溃时生成的。我在试着弄明白是什么引起的。如有任何意见，将不胜感激。谢谢.

Java运行时环境检测到一个致命错误：

SIGSEGV(0xB)在PC=0x00007F0E74C29E7D，PID=61623，TID=139695284021008

JRE版本:6.0_45-B06 Java VM：Java热点(TM)64位服务器VM(20.45-B01混合模式linux-amd64压缩oops）问题帧：V[libjvm.so+0x4e5e7d]java_lang_throwable::set_backtrace(Oopdesc*，Oopdesc*)+0x4d

Answer 1

这意味着它试图访问libjvm.so中的一个非映射地址（分段错误），即JVM内部。特别是C++方法java_lang_throwable::set_backtrace在尝试填充异常对象的stacktrace时。

这些东西通常是JVM本身中的bug。因为你仍然在使用Java 6，它已经到了生命的尽头，我建议你升级到一个新的版本，看看它是否已经被修复了。
