reason

Jmeter 2.10 后禁用了重新访问失败request
Jmeter 2.11后禁用了httpclient3和4的stalecheck

首先server开启socket，等待request访问。
当大量request并发进行时，request1先进入到socket，并且server通过socket读取了request1的一行，但这时request2也进入到socket并被server读取完毕，然后关掉了socket. 这时request1无法被server从socket读取stream，返回closedsocket

soulution

JMeterSocketClosed

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
