Increased memory usage with debian 11 & ruby 3.0.3

[johannesluedke]

Describe the bug
Memory consumption tripled when using debian:11.1-slim with fullstaq ruby 3.0.3. When switching back to debian 10 with fullstaq ruby 3.0.3 the memory consumption is low again.

To Reproduce
Linux distribution: debian:11.1-slim
Package name: fullstaq-ruby-3.0.3-jemalloc

Steps to reproduce the behavior:
We see the increased memory consumption with a real life workload

Expected behavior
Memory consumption is similiar when using fullstaq-ruby-3.0.3-jemalloc in debian:10.10-slim or debian:11.1-slim container
