09/10/2025, 1:07 PMI have self hosted growthbook. Today in the afternoon, I added few support groups with 100,000 entries and attached it to an experiment. After enabling the experiment, I am unable to open the dashboard. The /auth/refresh API is giving timeout. I restarted the docker compose but still same issue...Please help

09/10/2025, 2:30 PMafter much logging around, I see the process at 3100 (gb backend) is not returning any response when i hit using curl
pfa screenshot. 1st screenshot is response received from localhost:3000 and second screenshot is from localhost:3100.
please suggest on restarting the backend service or viewing log to debug further! I tried restarting the container using docker down and up command, but no avail!

09/10/2025, 3:47 PMWhen you say added 100k entries to an experiment, what do you mean?

09/10/2025, 3:48 PMi mean in savedgroups, created a list of user_ids that included 100k user_ids...and then attached it as "Force" rule in a feature key tagged to experiment

09/10/2025, 4:00 PMRight, I'm thinking that the large saved groups may be crashing the server. Try connecting directly to Mongo and removing them the DB. Then, restart the docker container and see if you can connect. I'm looking now to see if we've had any other reports/insights on Saved Groups perf.

09/10/2025, 4:11 PMI deleted the savedgroups, attached feature key and attached experiment key, but still the same issue.
I have a cdn in front of my hosted gb and invalidated cache too.
I noticed my cpu going up to 70% when I started the experiment with the savedgroup attached.....weirdly when I am switching to different mongo database (with name growthbook copy) and create new container to move traffic to this container, the dashboard is opening and cpu is going back to 10%...so I believe apart from just savedgroups, feature key and experiment key, something else might need to be deleted as well

09/10/2025, 4:38 PMOkay, so I completely disabled growthbook SDK in my web application. CPU is back to less than 10% and now growthbook dashboard is opening as well.....so I believe it has to be some other reference of savedgroup saved in some collection!!!
It seems there is some reference of this saved group elsewhere as well in mongodb... @strong-mouse-55694 do let me know in which other collection I need to remove savedgroup referenc.e...thabks!
