求助：ClientAbortException: java.net.SocketException: Broken pipe
用到的web框架：Struts2+Spriing3.0+hibernate3.0
部署环境：suse Linux+tomcat6.0+mysql，传输速度1M左右
具体操作如下：
选择文件进行上传时，文件大概是7.8M的XML，点击提交之后，无任何提示，直接跳转到“页面无法找到”如图
看tomcat的日志，在日志文件localhost-时间.log找到该异常：

然后在struts2指定的临时目录中找到了刚才上传的文件，只有8K左右
好像是链接被重置了，如果上传小于1k的文件没有该问题
我用Wireshark抓包工具抓了一下包，发现在收到几个包之后收到了rest包，这个问题解决了3天了毫无结果，那位大侠知道的话，请指点一下，小弟万分感激！

解决办法是在环境变量中设置：_JAVA_SR_SIGNUM=12 基本就可以解决。
sun的解释：
－－posted by: cooper
Below is a clipping from Sun on working around JVM crashes under high
thread counts in the JVM 1.3 for Linux
On Linux, use a larger signal number for hotspot thread
suspension/resumption handler. The signal number being used is
specified by environment variable _JAVA_SR_SIGNUM. Setting it to a
number larger than SIGSEGV (11) will solve the problem. A good number
to use is 12, which is SIGUSR2. Using signal 16 to work around the
problem might have potential problems. So on tcsh, "setenv
_JAVA_SR_SIGNUM 12" can solve the problem.
