3.14.0d Docker Version:
18.06.1-ce If using docker-compose, version:
1.22.0

OS: MacOS High Sierra 10.13.6 16GB RAM

Docker Command to start Zalenium:
I use docker compose to start the service

 version: "3"
services:

          - TESTINGBOT_KEY
          - TESTINGBOT_SECRET

Expected Behavior -

The test should run without random error

Actual Behavior -

Now I am getting random test failure. It looks like the request to Selenium does not get through and yield a 500 error, this triggers the failure. I have 4 tests in parallel, and 50 test cases in total. There are about 4-5 tests will fail randomly due to this error. Here is the stacktrace of the error,

per @diemol 's comment on slack, I also attached the docker logs zalenium here for debugging, I think it might be related to the OKhttp3 issues people reported earlier?

I attched the whole logs here docker-zalenium.log Also, I attache my github repo that with the code that may be helpful to reproduce the issue. https://github.com/DowneyTung/golem/tree/H5G

@DowneyTung when it fails, does it always fail in the same action? Clicking, uploading a file, etc... I see in the stacktrace that it fails while taking a screenshot, but I wonder if that is always the case.

Oct 29 '18 19:10 diemol

@diemol it is not happening for the same action. Sometimes when i wait for a attribute to display...so I think it happened randomly.

Oct 30 '18 18:10 DowneyTung

Hi team!

With that bulk of testing you should really look at your ecosystem. Running a heap on a container will undoubtedly give you some random occurrences because the vm simply cant cope with the strain.

What we should be looking at is your machine performance whilst these parallel runs are occurring. Zalenium is a great tool, but as the developers themselves state, this is a throw away grid to be run locally and they suggest alternative cloud testing solutions like BrowserStack/Saucelabs.

Multi-threading and running tests in parallel can get tricky. It is highly recommended that one restarts/refreshes the hub as well as the node regularly. This is to ensure any memory leaks are taken care off among other things like browser temp files etc.

I hope this helps you. Cheers SP

Hi @DowneyTung , if you are using TestNG, then try with version 6.14.3. I saw a similar problem when my tests were running with TestNG version 6.11. And it worked without using the ZALENIUM_EXTRA_JVM_PARAMS with TestNG 6.14.3.

I actually found this below config to be the most stable with my framework. I have over 3000 tests.

Selenium server: 3.12.0 Docker version 18.06.1-ce, build e68fc7a elgalu/selenium:3.12.0-p10 dosel/zalenium:3.12.0g

Docker command: docker run --rm -d --name zalenium -p 4444:4444 --log-driver=none -v /var/run/docker.sock:/var/run/docker.sock -v --privileged dosel/zalenium:3.12.0g start --desiredContainers 15 --maxTestSessions 99 --videoRecordingEnabled false --maxDockerSeleniumContainers 16 --seleniumImageName elgalu/selenium:3.12.0-p10

@mza031 I am not using TestNG.... I am using python...but will definitely try the version you are using...

Nov 02 '18 17:11 DowneyTung

I have been getting a similar issue (also intermittently, and not occurring on a specific action), it no longer occurred when rolling back to 3.14.0g but began occurring as soon as I rolled forward to 3.141.59a

Hi all, We need your help, we know that some people are bumping into this issue, so we would be grateful if someone provided a test suite that we could use to reproduce the issue.

It could be something where the instructions are "you need to run this at least 100 times to get the error" or something like that, it does not need to be an exact test case that reproduces it 100% of the times. Ideally it should be a GitHub repo link where we can just run a command to run the tests.

What we know so far:

ZALENIUM_EXTRA_JVM_PARAMS=-Dwebdriver.http.factory=apache does not work anymore because since Selenium 3.141.0, the Apache Http Client was removed from Selenium itself.
The issue seems to be this one, but we haven't figured out under what conditions it happens, and what to do when it happens.

Dec 19 '18 14:12 diemol

@DowneyTung I tried to use the repo you linked above, but it seems the tests are not working anymore, could you update them please? (Cool framework by the way!)

Dec 19 '18 14:12 diemol

@diemol Sure. I haven't update the code for a while as I moved the repo to private due to company privacy policy. But I will update the code to make it workable again for the public users. Will let you know once I am finished. Thanks

Dec 20 '18 04:12 DowneyTung

@diemol I updated the test code and you can check it out and see whether it works for you. Let me know if you have any questions https://github.com/DowneyTung/golem/tree/H5G

Dec 20 '18 19:12 DowneyTung

@diemol Am facing the same issue,am running a protractor test in zalenium and my test will be taking close to 180 seconds to complete,but the container get closed with error message as below around 120 seconds,Kindly let me know the workaround for this issue.

I got the same error, when I run a test with more than 6 minutes.

I am having the same issue as well. Is there anything I can do to help?

Apr 30 '19 11:04 ablok

Yes, me as well. Running Docker for Windows. Firewall disabled. docker run --restart unless-stopped -ti --name zalenium -p 4445:4444 -e ZALENIUM_EXTRA_JVM_PARAMS="-Dwebdriver.http.factory=apache" -v /var/run/docker.sock:/var/run/docker.sock -v /e/ZaleniumVideos:/home/seluser/videos -v /e/ZaleniumShare:/tmp/node/home/seluser/Downloads --privileged dosel/zalenium start --screenWidth 1920 --screenHeight 1080 --timeZone "Europe/Berlin" --desiredContainers 6 --videoRecordingEnabled true --keepOnlyFailedTests true --maxDockerSeleniumContainers 10 --maxTestSessions 6

Apr 30 '19 11:04 SomeCoolName444

For me disabling the firewall on the linux server resolved the issue.

Spoke too soon seems like the issues weren't resolved.

Apr 30 '19 11:04 tomerzel87

I am also getting this error in almost every test run, what can I do to help resolving this issue? What information you need that might help?

Oct 15 '19 13:10 ls-sergii-buchovskyi-zz

Increasing the resources allocated to the browser pods helped quite a bit.

  cpuRequest: 800m
  cpuLimit: 4000m
  memRequest: 700Mi
  memLimit: 5Gi

Oct 15 '19 16:10 zackb

Thanks for the suggestion to increase resources allocated to pods running browsers. I'll give it a try, too. Since some time already we're also facing trouble in our build pipeline with executing tests with Zalenium. The problem is the same as this issue here.

What kind of information you'd need to debug this issue?

Oct 16 '19 12:10 tpiekarski

I'd recommend to hook Prometheus or a similar tool to monitor performance, then you can correlate failures with performance metrics and find out how much more or less you need to increase.

Oct 16 '19 12:10 diemol

We are experiencing this as well. Generally we are running 6-10 containers and it seems to happen most often when running a test that has to do some kind of polling on a UI screen.

The strange thing is we've had some instances work for a few hours (obviously other issues there!) and other times, like the past 2 days, it will fail after only a few minutes. Today made it 4 minute and 33 seconds.

In our case, it occurred when we executed some arbitrary javascript due to a click event not being possible. It's difficult to tell if the click was blocked by this same issue, or something related to the page (need to tweak our error logging).

Including trace because one method call is different, and a few line numbers are different, in case it matters:

is it possible to use something other than okHttp at present? e.g apache http factory? Also could this be caused by some version of java running on the jenkins slave(s)?

Oct 23 '19 08:10 symonk

also note: this is not caused entirely by 'parallel' runs because I tested it with a sequential single process/thread test run, it still occurs there. We can also erradicate that it is a single command exec causing it, as mine varies on every failure.

its just a random command going through self._exec(command) that dies once every so often.

@diemol is this a selenium issue? I'm not so sure its a 'zalenium' issue?
