Possible memory leak.
Hello. I have a problem with my server having its RAM usage slowly increasing until it crashes. It might be because of plugins like ImageFrame but I'm not too sure.
Here is the spark profiler link: https://spark.lucko.me/8FDxHgSNVn

spark is a performance profiler for Minecraft clients, servers, and proxies.

These are not magic values. Many of these settings have real consequences on your server's mechanics. See this guide for detailed information on the functionality of each setting.
✅ Your server isn't lagging
Your server is running fine with an average TPS of 20.

My server is using too much memory
My panel says my memory usage is high all the time.
Your server runs in the Java Virtual Machine (JVM), which has significant overhead & tries to effectively use ALL of the memory assigned to it.
Memory usage from "htop", Task Manager, or your server panel is the total consumption of the JVM, not just your server.
My server is lagging & I think it's memory related.
It's much more likely that you are bottlenecked by your CPU, disk, or some inefficient mod/plugin.
Rule of thumb, servers should have anywhere from 4GB to 12GB of memory, with 8GB being the 'sweet spot'.
If you're heavily modded, add 4GB to that.
Too much memory can be a bad thing. Don't exceed these caps unless you really know why you're doing it.
Troubleshoot your server the right way: use Spark & send us a report.
My server is randomly terminated unexpectedly.
Setting your server to use 8GB does not mean that Java won't exceed this amount.
As a rule of thumb, allow your system/container about 1-2GB (possibly more) overhead outside of the server.
If you're on Linux & can SSH into the system, check your kernel logs. They will report any incidents of OOM.
I want to use swap to allocate more memory.
Don't. Swap is not free memory and using it can negatively impact performance.

Most likely isn't a memory leak
i will update the thread if the server crashes. we used 3gb before and it crashed, and now we upgraded to 4gb and still testing it out
ok, i got a snippet of the crash

Treasure maps are the cause
Easiest fix is just disable them in papers config
vanilla treasure maps?
i do install a datapack that adds structures with their own treasure maps, and i also installed imageframe plugin
but i have disabled those and it still crashes
Treasure maps in general
ah
i'll update the thread in a few hours to see
The server is running in offline mode.yikes
didnt even see that lmao
so, been running the server in a while, and other than full memory usage which is a non-issue apparently, the server seems to run fine now with disabled treasure maps
i think i can close this thread now, thanks
