http://issues.apache.org/bugzilla/show_bug.cgi?id=40750 Summary: Behaviour when TCPSampler sockets are closed by remote host Product: JMeter Version: 2.2 Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: HTTP AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] Problem: ------- When the socket connection used by TCPSampler is closed by the host, the socket will time out, but leave the connection in a "viable" state. Jmeter does not attempt to check for this. If the Thread Group is looped, the same connection will be reused. But it is closed from the host end so all the threads will just time out! As a quick fix for myself, I modified TCPSampler.java. I changed getSocket() to always attempt to close any Sockets already in the cp map, and then create a new one. Suggestions: ----------- As suggested by sebb, if there is no way of automatically detecting and resetting the connection, an option might be used to determine the behaviour if a timeout occurs. This is probably the way to go since we cannot predict the behaviour of every protocol??? THe Jmeter.log is below with TCPSampler debugging on. The actualy data sent and recieved has been removed (just in case).
