Fopnu is now consuming 8 GB of RAM on my system. Is there anything I can look at or adjust to lower that down, I don't recall Fopnu gobbling up so much RAM previously.

did you update recently?
when did you notice the increase?
how much is in your library?
do you run any channel? lots of people in them?

I dont run any channels but I have almost 9TB in 123,000 files and I use about 2-3GiB
