Possible Memory Leak in FAH client

The FAHClient.exe process alone is taking nearly 10GB of memory.
Restarting FAH did not resolve the issue; the FAH process allocated nearly 10GB of memory immediately after startup.
OS: Windows 11 Pro 24H2
FAH: Version 8.4.9

What you are describing is not a memory leak. It is excessive memory usage.

We can reproduce this all the time after we restart the pc with paused WU. FAHclient does something at that point to take all this memory. Dev is aware of it, not sure when the fix will be implemented.
Memory usage usually normalises after a while, or after you finish the WUs

I see. Just out of curiosity, what would be a reasonable, stable memory usage amount for the FAHClient? It appears that it still consumes 1-3GB of memory even after running for a while.
