You can limit the memory used by the server.
What's your startup flags
dont look at panel usage
if u are
!oom
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.
