------解决方案--------------------
这两天weblogic服务器一直无缘无故死掉.一查看是默认WEBAPP没有了.查看错误是too many open files 在网上找了半天终于有所收获,有如下解决方法:
1、ulimit -n 8196 加大linux最大打开文件数,不过这个试过好像不太管用.
2、echo "10240 " > /proc/sys/fs/file-max
第二种方法好像更管用。先试试看。。真不想重新编译linux内核
下面这个是晚上瞎转在网上看到的
以下适合redhat linux 2.4
Linux 内核有时会报告“Too many open files”，起因是 file-max 默认值（8096）太小。要解决这个问题，可以 root 身份执行下列命令：（或将它们加入/etc/rcS.d/*下的 init 脚本。）
# echo "65536 " > /proc/sys/fs/file-max # 适用于 2.2 和 2.4 版内核
# echo "131072 " > /proc/sys/fs/inode-max # 仅适用于 2.2 版内核
