Dear Wiki user, You have subscribed to a wiki page or wiki category on "Jmeter Wiki" for change notification.
The "JMeterSocketClosed" page has been changed by Philippe Mouawad: https://wiki.apache.org/jmeter/JMeterSocketClosed New page: == Connection Reset since JMeter 2.10 ? == If you upgraded recently to JMeter 2.10 or 2.11, you may have noticed increased errors of this type: * Socket closed * Non HTTP response code: org.apache.http. * NoHttpResponseException (the target server failed to respond) === Explanation === The increase of this type of errors can be explained by two settings changes: * retry of failing request (idempotent) has been disabled in JMeter 2.10 * stale check in HTTP Client 3 and 4 implementations has been disabled in JMeter 2.11 === Why these changes? === Previous retry default settings led to increased number of Requests in certain type of failures Previous stale check was a bit expensive, as it applied to every sample.That is why the default was changed to disable it. Retry or stale check can hide issues on Server configuration: Server failing to handle correctly Keep-Alive header Overwhelmed server refusing connection, retrying can increase load === Changing configuration: === If you think this server behaviour is OK, then configuration can be changed in two places: ==== Enabling retry ==== For HttpClient 4, in user.properties set : httpclient4.retrycount=0 For HttpClient 4, in user.properties set: httpclient3.retrycount=0 ==== Enabling stale check ==== 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 ==== New setting in JMeter 2.12 ==== Upcoming version of JMeter will add a setting to add connection timeout if the server does not send Keep-Alive headers This value is in milliseconds: * httpclient4.idletimeout=<> === Interesting links: === * https://issues.apache.org/bugzilla/show_bug.cgi?id=56119 * http://stackoverflow.com/questions/4798461/cneonction-and-nncoection-http-headers === Author: === Philippe M.
