1649969 - HTTP3 memory leak on nightly

Status: RESOLVED INACTIVE

(Core :: Networking: HTTP, defect, P2)

Description

[g]

Attachment: memory-report.json3.gz

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

I enabled http3 on nightly to test the feature and I started having a memory leak which lead to system crashes.

Actual results:

Firefox will start to consume more and more ram until my computer crashes. This happens even on an empty session with no websites loaded while the browser is just idle.
I restarted in safe mode, all addons disabled, and the problem still persists, so no an addon problem.
On a clean profile I get no problems.
After I disable http3 everything gets back to normal.
I attached a memory log when firefox started to consume more ram.

Expected results:

Http3 should not cause a system crash.

This should have been fixed in bug 1648553. The bug landed at about the same time as this report.

artymka1, can you reproduce the issue on a newer versions of Nightly?
