1425324 - Websocket connections drops each 15 minutes

Status: RESOLVED INCOMPLETE

(Core :: Networking: WebSockets, defect)

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171130143349

Steps to reproduce:

I regularly use notebooks to write code. They use websocket to maintain connection with the server ( https://github.com/spark-notebook/spark-notebook is a good example ). In Firefox Quantum when I opened a tab with spark notebook and then switched to another tab for 10-15 minutes Firefox drops websocket connection to the notebook, so I have to close and reopen it again. As I spend a lot of time analyzing data and coding this way I had to switch back to Chrome


Actual results:

In Firefox Quantum when I opened a tab with spark notebook and then switched to another tab for 10-15 minutes Firefox drops websocket connection to the notebook, so I have to close and reopen it again. 


Expected results:

All websocket connections in the tabs should be opened, even if I spend an hour or two in another tab (it is quite common for me to have many Spark-notebooks opened and switching between them).

Hi, I've tried to reproduce this with running Spark Notebook on my laptop, but I can't reproduce this.
Is there any public web site that can be used to reproduce this problem reliably?

Thanks.

I cannot reproduce it. We either need a link to a site where we can reproduce the problem or you could provide a log as described here: https://developer.mozilla.org/en-US/docs/Mozilla/Debugging/HTTP_logging

The problem is that 10-15 minutes of logging can produce huge logs. Try to log following modules sync,timestamp,nsWebSocket:5,nsHttp:5,nsSocketTransport:5. To minimize log size use only as many tabs as really needed and try to keep firefox idle during those 10-15 minutes.

@:michal

Sorry, I was on the vocation. The bug is real, I need a week to deal with some urgent issues and then I will have some time to make logs for you.

To keep the size of logs small, use MOZ_LOG and MOZ_LOG_FILE environment variables and add rotate:300 to the list of modules.  If you want to use about:network#logging, it's fine too - then please zip (or xz) the log files before sharing.

Thanks.
