[BUG] Unraid / ClickAndLoad / libmini_racer.so: Out of memory

[Staufahrer]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Running :latest within Unraid.

Using the ClickAndLoad Addon to add new downloads to Pyload leads to an error message.

The out of memory message seems to be misleading, because the system sits at 4GB out of 32GB and even adding "--memory=2G" to PyLoad does not change anything. This affects atleast 2 different NAS / Docker / PyLoad installations in different houses.

Expected Behavior

Download of ClickAndLoad content/files should be added to Queue and download should start.

Steps To Reproduce

1. From a Windows client redirect the ClickAndLoad data to Pyload, a.e. with "netsh interface portproxy add v4tov4 listenport=9666 listenaddress=127.0.0.1 connectport=9666 connectaddress=YourPyLoadIPHere".

2. In-PyLoad Logs will show the connection/transfer attempt:
   2025-08-23 19:54:38 DEBUG pyload ADDON ClickNLoad: Connection from YourClientIP:RandomPort

3. Console will show the already mentioned "libmini_racer.so: Out of memory" error.

@Staufahrer
I ran into the same issue. So I built a image by myself (podman instead of docker), this will work very well.
Give it a try, as long the official image is not rebuilt. Howto is shown in README :)

Can be closed, this issue is unrelated here.
This have already been fixed in pyload/pyload@3ae0fe4.
