Appwrite API and Console keep failing

i have an appwrite docker container.... Somehow today it suddenly startet to keep failing every half an hour to two hours. The server is reachable via ping but the appwrite console / api is not working... It just times out. I also noticed that even after the service "fails" the ram usage of my server keeps rising... I also tried just scaling up the machine the container is running on but this didnt help. The machine has 8GB of Memory, 2 CPU Cores and about 13 GB of free storage remaining. the stats i appended are taken while the service has already failed. what things can i check to find out what the issue could be?

Every bit of help is welcome
