PhantomJS disconnecting because no message in 10000 ms when set to single-run

[ciwchris]

When running tests on our build servers on random runs, seemingly, no tests run and karma exits with the message:

Disconnected (1 times), because no message in 10000 ms.

So far I've only been able to reproduce this when using the --single-run option and only on our build servers, on my dev box I've never experienced this. Here's the version info on the servers:

Windows 2012 R2 node: v4.4.5 karma: v0.13.22 karma-phantomjs-launcher: 1.0.0 phantomjs-prebuilt: 2.1.7 PhantomJS: 2.1.1

On one build server it seems the tests run about 50% of the time, on the other server it's less than 10%. Also, if I set log-level=debug then it raises the percentage to successfully running over 90% of the time on both servers. Here's the debug info from a failed run (with names stripped):

If I change the karma config on the build servers to use Chrome then the tests always run successfully. I've tried previous versions of karma-phantomjs-launcher and phantomjs-prebuilt, but I haven't noticed a difference. I'm not sure where to go from here.

[boschni]

Try to set karma's browserNoActivityTimeout setting, that worked for me: https://github.com/karma-runner/karma/blob/master/docs/config/01-configuration-file.md#browsernoactivitytimeout

[ciwchris]

@u-nikos thanks for the suggestion. I'll give it a try when I'm back next week.

[zsims]

Any luck? There's several issues raised around this. Most solutions seem to land on bump the retry count + timeout.

Wonder if this related to IPv6, as all the machines I've seen this on have localhost resolve to ::1.

[ciwchris]

@zsims, thanks for the bump.

I increased the timeout to 30 seconds and the issue persists.

localhost does resolve to ::1. Is there a solution, besides changing the machine's network settings?

[SPSpwetter]

browserDisconnectTolerance will cause it to attempt to reconnect, which is better than a timeout. Though your log is indicating something else.

[chrstnbrn]

I just had the same problem. It only occured on my continous integration server while working fine locally. I tried to increase the browserNoActivityTimeout but still no tests ran. I finally fixed this by removing the plugins property from my karma config.

[jeffkynaston]

Had the same issue today - worked locally on mac OSX sierra but ran into the error on our CI server (redhat) @chrstnbrn's suggestion fixed the problem for us

[ciwchris]

@chrstnbrn thanks for the suggestion, but we already don't have a plugins section in our config, neither when running locally or on our CI server.

[zsims]

Using Chrome instead of Phantom JS was the only way I was able to resolve this.

[ghost]

I have a similar issue which just started occurring today.

The tests start to run but then after a certain number of tests (it always looks to be around the same number) I get the [PhantomJS 2.1.1 (Mac OS X 0.0.0)]: Disconnected (1 times), because no message in 10000 ms. error.

All tests ran successfully a couple of days ago and haven't changed since.

It doesn't look like I'm running out of memory and I do have swap enabled.

[bkardol]

Running into a similar issue on our build agent on VSTS.

We have a couple of retries, but it disconnects every time. We added the following properties to the config file:

        browserNoActivityTimeout: 100000,
        browserDisconnectTolerance: 2

[alex7egli]

I had a similar issue on Windows 10, nodejs 4.6.1, karma 1.1.2, phantomjs-prebuilt: 2.1.8. I fixed it by changing my karma config preprocessors option from:

preprocessors: {
        'app/**/*.js': 'coverage'
    },

TO

preprocessors: {
        'app/!(bower_components)/**/*.js': ['coverage'] //track test coverage of our JS code
    },

[ciwchris]

@alex7egli thanks for the suggestion. I checked, we aren't using any preprocessors.

[ErikSchierboom]

I'm also having this problem. Excluding bower_components and jspm_packages didn't help. Strangely enough, if I pass --no-single-run, I don't get the timeouts.

[Jossif]

We are having the same issue running tests in Chrome on VSTS:

any suggestions ?

[Ks89]

I have the same problem with Appveyor, but not on my mac.

[zeevm]

Same here: Using phantomjs locally works fine, on a VSTS CI server if I use single run it gets disconnected with no message error, if I don't use single run it works on the server but then the build plan is obviously stuck because karma didn't exit.

Anyone made any progress on that?

[Ks89]

@zeevm exactly. You explained in a better way my problem XD

[zeevm]

Going deeper I've enabled all debugging options available and the scenario is always the same, karma serves all files to PhantomJS up to karma-test-shim.js and then the process gets stuck, I assume the browser stops responding and karma disconnects it after 10 seconds. It's always the same file that gets stuck karma-test-shim.js I've started adding tracing outputs in it to see where exactly it hangs in the file and turns out it's a nasty hisenbug, with the rightly places log messages in the file, the browser doesn't hang and the tests run properly, not entirely deterministic though, about 40-60% success.

[rayzor65]

I still get the issue ("Disconnected (1 times), because no message in 10000 ms") after trying the following:

Increase browserNoActivityTimeout, waits longer but still dies Increase browserDisconnectTolerance, still dies at the same place Increase browserDisconnectTimeout singleRun true or false does not make a difference

Using phantomjs: 2.1.1 and karma-phantomjs-launcher: 1.0.0

I noticed that when I skipped a large chunk of tests they did run. It's not failing on a particular test my theory now it has something to do with the amount. Any suggestions what I can try? Tweak my VM perhaps?

[rayzor65]

I managed to fix my issue by increasing the timeout of mocha. Hopefully this helps someone else! eg. client: { mocha: { timeout : 20000 } },

[Ks89]

I still get the issue also with an higher timeout

[bitencode]

Just started having this same problem last week: phantomjs 2.1.1, karma 1.3.0, karma-phantomjs-launcher 1.0.0. I've tried most of the suggestions here, nothing has helped yet. Works fine on my mac, fails with the timeout message on our linux/Jenkins build system. [Sorry I'm not more helpful - if I find something, I'll add it here]

[iheartpaypal]

I was also running into this issue, and I discovered it was because I was (for some reason) missing the entry for localhost in my /etc/hosts file, which PhantomJS uses when it runs.

I added 127.0.0.1 localhost to my /etc/hosts, and it fixed this problem for me.

[vinylhero]

Short term fix as i'm also experiencing this issue, but try changing the port number you are using your karma tests on. I.e change

config.set ({
    port: 9876
});

I put mine to 9877 until it stopped working and then to 9878. This should work short term to get you working but need a proper fix

[vinylhero]

Changing the settings fixes the issue for a short period. I have changed port and log levels but both eventually fail again.

[androticus]

@iheartpaypal my hosts file already has entries for both 127.0.0.1 and ::1

@ErikSchierboom i tried the --no-single-run and that ran some of my tests (100/130), then the command line window just hung, no further progress no error

[rupendra-sharma]

Hi

I am getting the same issue with Chrome and Karma. [33m27 01 2017 15:01:51.287:WARN [Chrome 55.0.2883 (Windows 10 0.0.0)]: [39mDisconnected (1 times), because no message in 1000000 ms.

Execute Karma from command prompt: C:>/ node node_modules\karma\bin\karma start marilyn.conf.js --log-level warn --no-auto-watch > MyTestLog920TestCase.log Surprisingly it worked for 920 test files but not more than that.

I do not have any plugin statement.

[developerX]

@rupendra-sharma @androticus are you guys using ui-router? What my issue was that ui-router had updated to (1.0.0-rc.1) when doing an npm install and the tests started failing out. I then switched back to the previous version of ui-router and everything runs perfect again.

I hope this helps anyone else that runs into the same issue. I spent a lot of time tracking this down hahah

[lbennett-stacki]

I bumped into this issue today on GitLab CI.

It seems to be an issue with the phantomjs-prebuilt as it runs fine when installing the PhantomJS binary manually on the CI server (I used a docker image).

Update: Actually, I take that back. It works fine on node:7 but not node:alpine, so is probably underlying dependencies issue that isn't tracked with npm.
