服务器出现broken pipe ,connection reset解决方法

  linux下webloigc经常出现broken pipe,socket....connection reset错误.
  有有可能是linux的线程机制会产生JVM出错的问题,特别是在连接高峰期间经常出现这样的问题,tomcat在linux下也出现类似情况。
  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:

  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.
  上次有人问在连接数据库的时候也出现过connection reset错误,这有可能是连接没有正常释放(不一定是程序的问题),最好在连接迟中设置无效连接超时的最大值。
