I haven't been playing iRacing for a couple of weeks due to a summer break, but have the fanaleds program running at windows start (and almost never shutdown / reboot).
After I updated fanaleds I recently noticed that it seems to have a memory leak (again).
Once I close and restart it again it starts out by using around 10MB, but when I return to my computer the next day it was using 2+gb
Also now I restarted the program like 15 minutes ago, haven't run a racing game or something and now it's up to 40+mb already.
I had it with one of the early versions as well when I think it was caused by some xml library you guys were using.
I'm using a G27 wheel if that matters btw.
This it the earlier report when I had a similar issue:
