Growing memory over time / Memory Leak

[axotion]

Hi,

I've been encountering a weird behaviour on k8s with some nodejs apps and pyroscope, as over the time, memory is growing indefinitely.

I've tried different docker image base OS (Alpine with node 18, node:20-bullseye-slim), setting pods replicas on k8s to 1, but without a luck.

Installed Pyroscope version

"@pyroscope/nodejs": "^0.3.11",

Usage in code

Memory usage over time

As it's getting more strange, the pyroscope itself does not seem any memory growth

FWIW, I reported something very similar in #28. I never got a resolution.

Yea I saw it, but IIRC the issue you raise was on the version when this package was still using google pprof. They switched to datadog pprof.

And that surprised me. This package is basically a wrapper for datadog pprof, and I've been using datadog profiler in nodejs environment for years and tbh - never had such a problems
