你好，正在试用FastDFS，做测试的时候遇到一个问题，100个并发下载文件时，出现了大量如下错误：

这个问题是否是storage的配置造成的？

storage的配置如下：
disabled=false
group_name=group1
bind_addr=
port=23000
network_timeout=60
heart_beat_interval=30
stat_report_interval=60
base_path=/data/fastdfs
sync_wait_msec=200
max_connections=2048
tracker_server=******:22122
keep_alive=0

客户端起了100个进程？
貌似问题出在客户端，客户端CPU负载太高导致的？
压力测试情况下，你查一下客户端的CPU负载情况

对，就是在客户端起了100个进程。
不过客户端服务器是正常的，就是storage服务器负载有点高

storage server硬件配置是怎样的呢？如内存、硬盘、CPU等。

测试环境的带宽为1G，服务器直接接到千兆交换机上，storage分为1个group，2台服务器。

2台storage server：2CPU (Intel E5310 1.6GHz), 4GB RAM, 73GB×2

storage server硬件配置还可以的。

max_connections=2048
最大连接数配置得太大，你分别修改为256和1024再试试？

好的，我先去试试。

多谢fish兄，将max_connection改为512以后就没有上述错误了。
