RE: How to diagnose NoHttpResponseException
Hi Phillippe, we have tried the 3.2 build and that has dramatically reduced the errors, still have a small number, but I will do some digging into those and I'll see if we can get the nightly build into our test.

Re: How to diagnose NoHttpResponseException
Hello, Those settings are related to your server keep alive timeout. But there are fixes in both JMeter 3.2 and nightly build. Can you give nightly build a try: - http://jmeter.apache.org/nightly.html Regards On Mon, Aug 7, 2017 at 8:43 AM, Antony Bowesman < antony.bowes...@williamhill.com.au> wrote: > I am using JMeter 3.1 and HttpClient4 > I have the following httpclient settings in user.properties > > httpclient4.retrycount=3 > httpclient4.validate_after_inactivity=2 > httpclient4.time_to_live=180 > > I have 5 load generators and each generator is running approx. 6,000 VU > across a number of different samplers. > > We are migrating away from a commercial product, so in addition to this > load, I have 3 commercial product load generators running the same profile > and the effective server load is 75% JMeter and 25% other > > We do not have any problems with the commercial product, which we have > been using for 3 years. > > CPU and memory are fine on the Linux JMeter boxes, but I am seeing > frequent NoHttpResponseException errors > > I know that the retry logic is happening as in the test I can see these > messages appearing and there are far more of these than actual errors and > it's logging my retry count as 3 > > 2017/08/07 14:36:09 INFO - > org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl$7: > I/O exception (java.net.SocketException) caught when processing request to > {s}->https://host:443: Connection reset > 2017/08/07 14:36:09 INFO - > org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl$7: > Retrying request to {s}->https://host:443 > > So, I've simplified the test down to a single machine and enabled debug > and run the test until I see the first error.
