4GB Plan locked to 900MB Java Heap (No Startup Flags access)

I am running a Paper 1.21 server on the Aglaea node. The panel shows my server has 4096MB of RAM allocated, and the container usage sits around 900MB. However, Java itself is hard-locked to ~800MB - 1GB. I confirmed this using a Geyser Dump and the /gc command. The JVM flags see…

I am running a Paper 1.21 server on the Aglaea node. The panel shows my server has 4096MB of RAM allocated, and the container usage sits around 900MB.

However, Java itself is hard-locked to ~800MB - 1GB.

I confirmed this using a Geyser Dump and the /gc command. The JVM flags seem to be forcing a low -Xmx value, regardless of the plan limit.

Evidence: Panel Usage: 900MB / 4000MB (22%) In-Game / Geyser Dump: Heap: 818 MB (303 MB free)

What I have tried: Checked the "Settings" and "Startup" tabs (Neither exist on my panel). Checked File Manager for user_jvm_args.txt or startup.sh (Files are missing). Attempted to upload my own user_jvm_args.txt with -Xmx4G (Ignored by the server).

My Question: Is there a specific environment variable or file I need to create to unlock the full 4GB allocation? Or is the Aglaea node hard-capped to 1GB Heap despite the 4GB Container limit?
