根据网上资料显示:我尝试过,貌似没解决问题

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。

在WIN环境变量中设置: _JAVA_SR_SIGNUM=12, 若Linux下用 export _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.
