Working on HAProxy Ingress Controller for Kubernetes (3.2.6) i see reloads every few seconds if the memory allocation is **not** above 500Mib. When running the footprint is very low, but if allocated less (\>500Mib) HAProxy keeps on reloading every few seconds. It does not enter ‘normal’ operations.

To reduce base consumption I set `maxconns` to 2020, as well as `tune.ssl.cachesize`globally.

```auto
 global-config-snippet: |
    tune.ssl.cachesize 2020
  maxconn: "2020"

```

HTTP/HTTPS frontends then have a limit of 1000 connections each.

Nevertheless this does not allow for lower requests/limits (i thought of something like 256Mib requests/limits). Is this expected?
