I am using JMeter 3.1 and HttpClient4
I have the following httpclient settings in user.properties
httpclient4.retrycount=3
httpclient4.validate_after_inactivity=20000
httpclient4.time_to_live=1800000
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. I get this in the log, but there is no
retry logged

The request sequence is for the virtual user is
1. Request 1 starts at 16:06:07.982
2. Requests 2...17 all successful with request 17 finishing at
16:06:32.134
3. Request 18 starts at 16:06:32.135 and throws this exception after an
elapsed time of 78ms, ending at 16:06:32.213
4. Request 19 starts at 16:06:32.213 and is successful
5. Requests continue to be successful
I don't see why this is not entering the retry logic. I have debug logging on
log_level.http=DEBUG
log_level.jmeter.protocol=DEBUG
so, I don't see why I don't see the log message
this.log.debug("Closing the connection.");
in the IOException handling at line 690 in DefaultRequestDirector
I can easily create these errors. Any help on how to diagnose further.
Thanks
Antony
