PiHole run in a docker container in Synology NAS
PiHole is not a DHCP Server (Nighthawk RAX200)/dev/shm) ahead: 98% used
Does it make sense to move the DHCP Server from Router to the PiHole Docker Container to reveal clients and spread the requests to them?

Your rate limit is as follows:
RATE_LIMIT=29000/10
Your memory may be consumed by the massive number of domains you have in gravity:
gravity_count 14996146
The more entries on blocklist, the higher your memory use.
[2023-10-18 10:30:06.565 1921M] WARNING: RAM shortage (/dev/shm) ahead: 98% is used (/dev/shm: 66.2MB used, 67.1MB total, FTL uses 66.2MB)

Let's take a look at the most recent 24 hour activity. What are the outputs of the following from the Pi terminal:
echo ">stats >quit" | nc localhost 4711
echo ">top-clients >quit" | nc localhost 4711
echo ">top-domains >quit" | nc localhost 4711
echo ">top-ads >quit" | nc localhost 4711
echo ">querytypes >quit" | nc localhost 4711
echo ">dbstats >quit" | nc localhost 4711
echo ">overTime >quit" | nc localhost 4711

Thanks jfb!
yes I changed my rate limit back to this value after pihole nearly immediatly went the shm issue. Thought way to many requests filling up the pihole-ftl.db... I deleted (or lets say renamed) this .db file to get pihole back working (.db file was already around 900MB in size).
yes I thought there are no limits in domain numbers theoretically, therefore took many lists from https://github.com/RPiList/specials/blob/c2101783fa3cd99ff4ee52c2a2fa397853b9e71c/Blocklisten.md
can you tell me where I do have to enter the echo statements in the docker container window?
If you aren't able to use the Synology GUI to run the commands you need to execute them on the Operating System terminal.
Open a terminal window and execute:
docker exec Pihole /bin/bash -c "echo '>stats >quit' | nc localhost 4711"
Replace Pihole with the name of your container. Repeat the command using the commands requested by jfb (If you receive a permission error, add sudo)
