Question

我已经习惯了崩溃我的tomcat服务器。但我认为我根本没有做任何改变，似乎完全破坏了它。工作一分钟然后不工作。

我真的希望有人可以在这里帮助Catalina.out：

我有一个新的日志已创建，我以前从未见过，但它似乎认为它的东西很严重。很长的但是在这里：

Massive Error Log I've never seen before

Answer 1

您的JVM有SIGBUS。这可能是硬件问题，也可能是低级JVM代码错误。

siginfo:si_signo=SIGBUS: si_errno=0, 
si_code=2 (BUS_ADRERR), si_addr=0x00007f0a9bb06fe5

你的创业公司中有一个可疑的条目是-Djava.io.tmpdir =（即temp dir是空字符串）。可以对JVM做有趣的事情，虽然我没有测试它。也许可以这样做。

jvm_args: -Dcatalina.base=/lhome/me/tomcat6 
-Dcatalina.home=/usr/share/tomcat6 
-Djava.endorsed.dirs= 
-Djava.io.tmpdir= 
-Djava.util.logging.config.file=/lhome/me/tomcat6/conf/logging.properties 
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager

底线：我相信您的硬件出现故障。备份一切。

Answer 2

炸弹似乎发生在由java.util.zip.ZipFile.getZipMessage()调用的原生方法getEntry()中。 ZipFile遇到错误，并尝试构建异常消息。在重新加载过程中停止正在运行的webapp时会发生这种情况。

您是否移动了.war文件？这可能会导致问题。

这些问题难以诊断和修复。但是，问题很可能是 java.io.tmpdir未正确设置。 http://efod.se/blog/archive/2011/05/02/java-sigbus是一个类似的问题。

如果这不起作用，请使用apt-get升级zlib和OpenJDK，并强制解释ZipFile.getEntry()：

-X:CompileCommand=exclude,java/util/zip/ZipFile,getEntry

正如OSB Stats所说，不要相信你的硬件（虽然它不太可能是硬件问题）。

Answer 3

感谢所有在这里给予帮助的人。

然而我失败了我应该回答我自己的问题。虽然我仍然不完全理解为什么它会引起如此严重的例外。问题似乎在于我在数据库中删除了程序正在读取的表。该表中充满了程序用于编译其他数据的数据。一旦我重新填充了这张表，就可以了。

我不知道为什么这么简单的事情导致如此多的错误，并且从未在日志中显示为未发现的表错误。但是，我只能假设该程序试图使用空白数据运行，而这个人造成严重错误。

再次感谢那些提供帮助的人！
