Issue with Memory Not Being Released When module is Set to None in Stable Diffusion WebUI with ControlNet

[sanerone695]

Description:
When using the Stable Diffusion WebUI with ControlNet, I encountered an issue where memory is not released properly when the module is set to None. In contrast, when the module is set to a non-None value, the memory is correctly released after the process is completed.

Details:

Environment: Stable Diffusion WebUI with ControlNet.
Behavior:
When module is set to None, the memory usage increases with each run and is not released after the task completes.
When module is set to a specific value (not None), the memory is released correctly after the task completes.
Impact: This issue causes the system's memory usage to increase progressively with each task, potentially leading to out-of-memory errors or reduced performance over time.
Potential Cause:
It appears that some internal resources or cached data are not being properly managed or released when module is None. This might be due to certain resource management logic not being triggered or properly handled in this specific scenario.

Steps to Reproduce:

Run a task using Stable Diffusion WebUI with ControlNet, setting the module to None.
Observe the memory usage after the task completes. Notice that the memory is not released.
Run the same task with module set to a non-None value and observe that the memory is released correctly after completion.

first from what I can tell you're reporting an issue related to specifically ControlNet
this means that you will have a better chance of solving this issue if you report it directly to https://github.com/Mikubill/sd-webui-controlnet

clarify what you mean by "ControlNet, setting the module to None."
I'm not sure what you're referring to by module, as far as I am aware there is no module

do you mean with a ControlNet unit enable the Preprocess and Model set to None?

• does this issue happen without ControlNet (extention completely disabled from extension tab)
• dose this issue happen with ControlNet (extention enable) but not uses (no ControlNet unit enable)
• dose this issue happen with using ControlNet (at least one unit enabled)

how much does the system RAM increase
