open too many files Exception

阅读更多
今天在调程序的过程中出现了一个open too many files Exception,这个异常异常陌生,于是乎借助强大的搜索引擎,找到了解决的办法。

注意:可以举一反三的

1. ulimit -a 查看系统目前资源限制的设定。
[root@test security]# ulimit -a
core file size        (blocks, -c) 0
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
max locked memory     (kbytes, -l) unlimited
max memory size       (kbytes, -m) unlimited
open files                    (-n) 1024
pipe size          (512 bytes, -p) 8
stack size            (kbytes, -s) 8192
cpu time             (seconds, -t) unlimited
max user processes            (-u) 7168
virtual memory        (kbytes, -v) unlimited

通过以上命令,我们可以看到open files 的最大数为1024
那么我们可以通过以下命令修改该参数的最大值(其他参数值也可仿照着修改)
2. ulimit -n 4096
[root@test security]# ulimit -n 4096
[root@test security]# ulimit -a
core file size        (blocks, -c) 0
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
max locked memory     (kbytes, -l) unlimited
max memory size       (kbytes, -m) unlimited
open files                    (-n) 4096
pipe size          (512 bytes, -p) 8
stack size            (kbytes, -s) 8192
cpu time             (seconds, -t) unlimited
max user processes            (-u) 7168
virtual memory        (kbytes, -v) unlimited

这样我们就修改了系统在同一时间打开文件资源的最大数,基本解决以上问题。
