reason

Jmeter 2.10 後禁用了重新訪問失敗request
Jmeter 2.11後禁用了httpclient3和4的stalecheck

首先server開啟socket，等待request訪問。
當大量request併發進行時，request1先進入到socket，並且server通過socket讀取了request1的一行，但這時request2也進入到socket並被server讀取完畢，然後關掉了socket. 這時request1無法被server從socket讀取stream，返回closedsocket

soulution

Enabling retry
For HttpClient 4, in user.properties set : 
httpclient4.retrycount=1 
This will make JMeter retry once. For HttpClient 3, in user.properties set: 
httpclient3.retrycount=1 
This will make JMeter retry once. 

Enabling stale check
For HC4 Implementation: 
In user.properties
 
: 
hc.parameters.file=hc.parameters 
In hc.parameters set: 
http.connection.stalecheck$Boolean=true 
For HC3 Implementation: 
In user.properties: 
httpclient.parameters.file=httpclient.parameters 
In httpclient.parameters set: 
http.connection.stalecheck$Boolean=true
