运行java程序，出现open too many files的解决办法

[root@slave ~]# ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 16384
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 16384
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 10240

[root@slave ~]# vi /etc/security/limits.conf
添加一行
#<domain> <type> <item> <value>
* - nofile 16384

[root@slave ~]# vi /etc/sysctl.conf#Decrease the tile default value for tcp_fin_timeout connection
net.ipv4.tcp_fin_timeout = 30
#Decrease the time default value for tcp_keepalive_time connection
net.ipv4.tcp_keepalive_time = 1800
#Turn off tcp_window_scaling
net.ipv4.tcp_window_scaling = 0

# Turn off the tcp_sack
net.ipv4.tcp_sack = 0
#Turn off tcp_timestamps
net.ipv4.tcp_timestamps = 0
//修改tcp socks
重启系统
