Hello,
If ADG enables more large Filter rules, it will occupy a lot of system resources, affecting system stability, and ADG itself will not worry about memory usage, causing if the longer the ADG runs, the greater the resources it will occupy.
If possible, try adding a memory limit:
Add the procd_set_param env GOMEMLIMIT=100MiB GOGC=40 , on this configuration /etc/init.d/adguardhome.
