Server Implementation

Paper

Server Version

1.21.8

Describe the bug

I regularly receive the error message High memory usage detected, FAWE will attempt to slow operations to prevent a crash. even though my Java startup flags have the same value for XMS and XMX. This seems abnormal as I expect FAWE to handle available memory correctly with this configuration.

To Reproduce

1. Start the Minecraft server with FAWE installed
2. Set Java startup flags with XMS = XMX
3. Use WorldEdit or FAWE normally
4. Observe the high memory usage warning message appearing in the console

Expected behaviour

I expect FAWE to not show a high memory usage message if I properly set XMX and XMS in my Java flags. I expect FAWE to properly use all available memory without unnecessarily displaying this alert or slowing operations.

Fawe Version

FastAsyncWorldEdit-2.14.1-SNAPSHOT-1212

Checklist

• I have included a Fawe debugpaste.
• I am using the newest build from https://ci.athion.net/job/FastAsyncWorldEdit/ and the issue still persists.

Anything else?

Other users on forums and Discord reported similar messages even with proper memory flags. It may be a false positive or an internal memory management issue of FAWE.
