奇怪的master_peer启动问题

这几天在suse10下面配置oracle的enterprise manager的时候，master peer起不来，在rhel3下面一点问题都没有
起来的时候出错：

进程起来的时候怎么调用了agent_shutdown 函数？

master_peer.out显示错误：

1. Setup?select/poll?problem:?Bad?file?descriptor ??
2. ./master_peer:?error?processing?configuration

   在metalink下找到一个文章，需要设置把ulimit -n 2048，尝试设置成2048，还是不行，实在没办法，推出crt登陆，直接进root下，再尝试启动master_peer，居然起来了

   观察了一下，直接进root的时候ulimit -n的值是1024，而进oracle后再su到root的话，ulimit -n的值是65536，原来问题真的出在open files上面，metalink还是对的，只是suse10下面要设置1024才行，rhel3上面设置成8192都没问题

   是跟操作系统内核还是什么有关？这个open files参数起什么影响？
