这是linux系统内核线程问题 ulimit -a查看当前配置 需要优化则修改/etc/security/limits.conf
以下是范例

cat <<EOF >>/etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc unlimited
* hard nproc unlimited
EOF

cat <<EOF >>/etc/security/limits.d/90-nproc.conf
*          soft    nproc     unlimited
root       soft    nproc     unlimited
EOF

cat <<EOF >>/etc/sysctl.conf
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_max_syn_backlog = 4096
net.ipv4.tcp_max_tw_buckets=50000
net.nf_conntrack_max=6553600
net.netfilter.nf_conntrack_max=6553600
EOF

modprobe ip_conntrack

sysctl -p
ulimit -n
