That's clearly a bug in the server, and should be reported to the supplier. The cause is presumably unexpected input, but a server should protect itself against such things. As it stands, the server is vulnerable to DOS attacks... > > > JMeter 2.1 has no such problems with the test suite and doesn't hang the > server. > There were various changes to JMeter since then which have presumably changed the way it sends the requests. > > The testcase executes a SOAP/XML-RPC Request sampler (it POSTs an XML > document to webMethods), followed by an HTTP request sampler (again to > webMethods).

Im baffled by this. > If you can create a very short test case, then run it using 2.1 and 2.3.1, and use a packet sniffer to capture the HTTP traffic. Comparison of the traffic data should show the different requests, and perhaps point to why the server is OOMing. If you don't send the HTTP Request in JMeter, does the server still fail, e.g. if you access it from elsewhere? i.e. is it the combination of the requests, or does the XML request cause all subsequent requests to fail? > > Regards, > > Sonam Chauhan > > -- > > Corporate Express Australia Ltd. > > Phone: +61-2-93350725, Email: [EMAIL PROTECTED] > > > > > The information contained in this email and any attached files are strictly > private and confidential.
