环境说明：

提示：fork: Cannot allocate memory
解决方法：

Display Current Process Identifiers Limit On a Linux Based Systems

Type the following command at shell prompt:
$ sysctl kernel.pid_max
OR
$ cat /proc/sys/kernel/pid_max
OR
$ sysctl kernel.pid_max
Sample outputs:

kernel.pid_max = 32768

Allow for more PIDs on a Linux based systems

up to 2²² = 4,194,304

Type the following command:
# sysctl -w kernel.pid_max=4194303
OR
# echo 4194303 > /proc/sys/kernel/pid_max

You need to append the following config directive to your /etc/sysctl.conf
kernel.pid_max = 4194303

Please note that this hack is only useful for a large and busy server; don’t try this on an old kernel or on desktop systems.
