Some observations from local debugging:
I've been tracking this memory growth locally and wanted to share a few
observations regarding how these components interact during this state:

1: kwalletd6 behavior: It acts as a passive, event-driven daemon handling
incoming D-Bus requests. The rapid memory growth (~14 MB/s RSS in my
environment) appears to be a downstream effect driven by an unusually high
volume of incoming traffic—specifically continuous CreateItem and GetProperties
requests for org.freedesktop.Secret.Item.Attributes.

2: Client-side request frequency: Monitoring D-Bus traffic indicates that
plasma-nm (inside kded6) enters a high-frequency retry/polling loop under
specific conditions (such as syncing a specific Wi-Fi credential UUID like
{...};802-11-wireless-security).

3: Cascade effect: When this loop triggers at ~10ms intervals, session and
proxy objects are instantiated faster than the standard lifecycle cleanup can
process them, leading to high CPU load in kded6 and steady RSS growth in
kwalletd6.
