1524763 - Endless increase of Web Content and WebExtensions processes causes unnecessary swapping

Status: RESOLVED DUPLICATE of bug 1476032

(Core :: General, defect)

Description

[Ulf Zibis]

Attachment: Firefox Taskmanager.png

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:65.0) Gecko/20100101 Firefox/65.0

Steps to reproduce:

• 6 GB RAM
• Restore 150 tabs from restart.
• Only open 4 tabs to load.
• Do some work with that 5 tabs.
• Not much memory usage from addons, see attachment.

Actual results:

4 Web Content and WebExtensions processes slowly increase their memory usage
Each ~ 30 minutes RAM is exhausted and swapping starts.
After ~ 5 minutes of swapping there is up to 3 GB free RAM again.
If I use more than 5 tabs, the collapse happens more often.

Expected results:

Garbage Collector should be triggered earlier, so no swapping must happen.

Thanks for posting the information from Task Manager, can you also paste your information from your about:support?

I'm also not sure if this is a tabs issue or a WebExtensions issue so we'll start with the latter and go from there.

Could you include an anonymized about:memory report when you are swapping?

Attachment: memory-report.json.gz

Hi, today i was very difficult to come to the blocking swapping, hopefully my memory report will help.
