回复 1# wenble1984

这个情况有人反馈过。
这是系统打开的文件数过多等情况引起的。
如果是Linux系统，可以通过执行如下命令来调整系统参数：
sysctl net.ipv4.tcp_fin_timeout=1
sysctl net.ipv4.tcp_tw_recycle=1
sysctl net.core.rmem_max=16777216
sysctl net.core.rmem_default=16777216
sysctl net.core.netdev_max_backlog=262144
sysctl net.core.somaxconn=262144
sysctl net.ipv4.tcp_syncookies=1
sysctl net.ipv4.tcp_max_orphans=262144
sysctl net.ipv4.tcp_max_syn_backlog=262144
sysctl net.ipv4.tcp_synack_retries=2
sysctl net.ipv4.tcp_syn_retries=2

调整如上参数后，你再试试。测试结果请反馈一下，谢谢！
