For the past two months my server becomes less responsive for me the DM as the night continues. We play Wednesdays at 8 PM Central. By the end of the session it is nearly unplayable for me and some other players (while some players have no issues).
I have read the article on the recent issues with server instability. I have looked at out of date modules, reducing the number of actors being loaded etc. This is getting very frustrating as my local PC has a powerful CPU, (3900x) GPU (3080) and more RAM than necessary (64).
Is this still a server issue or should I be looking at my Foundry?
Also list out your Modules, it sounds like you have one that is leaking memory based on what you describe. I play for 5.5 hours each Saturday, and have never had Forge/FoundryVTT slow down on me at all (or for my players).
In addition, do you have large audio files? If so, check “Large File Streaming” on them individually, that vastly improves the audio handling in 0.7.9.
