You don't understand my point... I'm not going to trust someone that doesn't know about what it was running at, which is why I asked for specifics on how much RAM it was using. I'm not trusting some random that says, "yeah bro, totally cool, not a problem even though I have no idea about what the RAM was at or even what I would consider to be high, but trust me bro, it's okay. I am soooo vigilante on RAM usage on my server despite having no clue about the RAM usage, but trust me bro, I would know if it was leaking."

Even after a restart of my NAS where every container was freshly started the RAM consumption wasn’t higher than a month later after the restart (without restarting any of the docker containers). And that is why I can with full conviction tell that my SearXNG instance didn’t leak memory.

No, you can't, not unless you specifically paid attention to it, which you didn't, and that is clear by you not knowing how much it was using. It's possible that every time you checked your overall usage was just after a crash and the container restarting.

That's the reason I asked you to give me specifics on the RAM... because without you being able to provide it, ruled out whether I trusted your opinion.
