Node 24.0.2: Memory leak on fetch response .text() #58380
Description
Version
24.0.2
Platform
Microsoft Windows NT 10.0.26100.0 x64
Subsystem
No response
What steps will reproduce the bug?
const response = await fetch(url);
const text = await response.text();How often does it reproduce? Is there a required condition?
I detected the leak in a script with succeeding fetch calls (40/s).
After 10000 requests, or so, the script terminated with code 134.
Windows logs report EventName RADAR_PRE_LEAK_64.
I identified the source to await response.text().
I tried different alternatives to fetch:
- undici
- node-fetch
- https
But the leak persisted.
This may only affect arm64 systems, not sure if only windows 11. There are very few discussions about this anywhere and this comment
Following the comment I downgraded to lts 22.15.1 and the memory leak is slower to develop but it still creeps in.
What is the expected behavior? Why is that the expected behavior?
No memory leak.
What do you see instead?
Memory leak.
