I have the app that works as an autoresponder. It checks the database every minute to compare if messages should be sent to users, depending on the time passed from their signup date.
Number of autoresponder messages and number of users is constant from the last 7 days, but the usage of RAM is constantly growing.
The down peak occurred when I restarted the app. The restart freed the RAM, but after that point the app again is using more and more RAM.
Any ideas how can I flatten the RAM usage?
