严重的Tomcat撞车让我很困惑

Question

我已经习惯于破坏我的猫服务器了。但我认为我根本没有做任何改变，似乎完全打破了它。一分钟后就不工作了。

我真的希望有人能帮上忙-- Catalina.out：

我有一个新的日志已经被创建了，我以前从未见过它，但它似乎认为它很严重。很长的一个，但这里是：

我从未见过的大规模错误日志

Answer 1

感谢所有在这里提供帮助的人。

但是我觉得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造成如此严重的例外。问题似乎在于我在程序正在读取的数据库中掉下了一张表。此表中充满了该程序用于编译其他数据的数据。一旦我把这张桌子重新装好，就好了。

我不知道为什么这么简单的事情会导致如此多的错误，而不会出现在日志中的表中，而不是找到的错误。但是，我只能假设程序试图使用空白数据运行，而这个人导致了一个严重的错误。

所以再次感谢那些提供帮助的人！

Answer 2

你的JVM有SIGBUS。这要么是硬件问题，要么是低级别的JVM代码错误。

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

启动时的一个可疑条目是-Djava.io.tmpdir= (即temp是空字符串)。可以对JVM做一些有趣的事情，尽管我没有对它进行测试。也许这样做是可以的。

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 

一句话：，我相信你的硬件坏了。备份所有东西.

Answer 3

炸弹似乎发生在本机方法java.util.zip.ZipFile.getZipMessage()中，这是由getEntry()调用的。ZipFile经历了一个错误，并试图构造一个异常消息。这是在停止运行webapp作为重新加载的一部分时发生的。

你移动.war文件了吗？这可能会导致问题。

这类问题很难诊断和解决。但是，问题很可能是java.io.tmpdir没有正确设置。http://efod.se/blog/archive/2011/05/02/java-sigbus也是一个类似的问题。

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，不要信任您的硬件(虽然这不太可能是硬件问题)。
