@whimboo can you please help

whimboo · 2019-11-04T22:15:29Z

@mShubham094 you have a very outdated geckodriver installed. Please upgrade to 0.26.0 which should be much more stable, and should also fix your issue. Also without a trace log I cannot tell anything.

mShubham094 · 2019-11-05T00:59:18Z

@whimboo I have already attached the trace level logs as an attachment

mShubham094 · 2019-11-05T01:01:12Z

Attaching it again

mShubham094 · 2019-11-05T04:05:52Z

@whimboo I tried with 0.26.0 but may be because of compatibility with selenium version i am using, it is not opening the firefox browser itself. So, i tried using 0.24.0 geckodriver and i see the same Connection refused issue with more than 10 parallel firefox browser.

whimboo · 2019-11-05T07:37:06Z

Please find our support matrix here: https://firefox-source-docs.mozilla.org/testing/geckodriver/Support.html. You clearly have to run 0.26.0 to provide more details, otherwise we will have to close this issue. 0.24.0 is also no longer maintained.

mShubham094 · 2019-11-05T11:53:09Z

@whimboo I am not able to use 0.25.0 and 0.26.0 version because of the open issue #1617.

So, for now, can we check the issue with 0.24.0 version and see what is causing the problem to not run more than 10 parallel firefox browsers

whimboo · 2019-11-05T11:59:10Z

Then I would propose that you install the MSVC runtime for now. Otherwise and as already mentioned I will have to close the issue. We don't do any investigations on a not supported release.

mShubham094 · 2019-11-05T13:19:18Z

@whimboo i could proceed after MSVC runtime installation with 0.26.0 geckodriver version, but still i could not proceed with more than 10 parallel browsers. Attached the trace level logs
gecko_trace_logs.txt

The first log is with 15 parallel firefox browsers and the second logs is for 20 parallel firefox browsers.
gecko_trace_logs2.txt

whimboo · 2019-11-05T22:04:13Z

The log file is completely garbled. What you want is not to let all Firefox/geckodriver processes to write to the same log file, but use individual ones. Then please upload one of those logs which show a problem.

mShubham094 · 2019-11-06T08:42:46Z

I couldn't write each test case logs to different file, instead i have just 60 seconds logs from the time test case execution started for all 20 browsers. This logs looks like little bit understandable and i can see this error "DEBUG <- 500 Internal Server Error {"value":{"error":"timeout","message":"connection refused","stacktrace":""}}" and you can find the 60 seconds logs at
gecko_trace_logsFailure.txt

whimboo · 2019-11-06T10:03:06Z

Again, I would have to see it in separate logs. Otherwise I clearly won't be able to investigate the underlying reason of why geckodriver could not connect to Marionette. Please check with the Selenium community in how this would be possible. I'm fairly sure it is.

whimboo · 2020-04-16T05:43:29Z

No further response. Closing the issue.
