当ulimit已更改为unlimit时，java无法增加Wildfly的“最大打开文件数”
我正在用wildfly开发Ubuntu 16.04。我收到一个错误“由以下原因引起：java.net.SocketException:打开的文件太多”。所以我把ulimit改为ulimite，适用于所有用户
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 128429
max locked memory (kbytes, -l) 16384
max memory size (kbytes, -m) unlimited
open files (-n) 65535
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 65535
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
在/etc/security/limits中。形态
* soft nproc 65535
* hard nproc 65535
* soft nofile 65535
* hard nofile 65535
root soft nproc 65535
root hard nproc 65535
root soft nofile 65535
root hard nofile 65535
问题是，除了wildfly之外，另一个java进程获得了一个新的open files值（65535）
cat /proc/1717/limits
Limit Soft Limit Hard Limit Units
Max cpu time unlimited unlimited seconds
Max file size unlimited unlimited bytes
Max data size unlimited unlimited bytes
Max stack size 8388608 unlimited bytes
Max core file size 0 unlimited bytes

Max processes 128429 128429 processes
Max open files 4096 4096 files
Max locked memory 16777216 16777216 bytes
Max address space unlimited unlimited bytes

Max pending signals 128429 128429 signals
Max msgqueue size 819200 819200 bytes
Max nice priority 0 0

我已经重启了服务器。请告诉我如何解决这个问题

JBoss
ulimit的最大进程可以根据服务器接收的每日负载进行设置，但标准大小为65536，openfiles也可以设置为65536以上。我们对并发用户和每秒最大点击数进行了负载测试，以得出数字结论检查JBoss
ulimit：
