memory leak #22

slimefun version and addons: https://prnt.sc/dW2_3EQ7cnzM

HeadLimiter is increasing the memory a lot, my server barely restarted and already hit 25GB, and his normal is always 20GB, when it comes to night the server is almost 28GB, when removing the addon I noticed that there was no more increase in ram memory.

that's only 10m servers online, after a restart: https://prnt.sc/cmrP7uyzNpU4

my configuration: https://mclo.gs/VY3JiVB

Can I get a spark report from when the server starts for 15min

J3fftw1 commented 7 months ago

it looked like you deleted your spark report comment. I need some information. Can you run the following commands and let them finish before starting the next command. /spark profiler start --thread * --timeout 900 /spark health --memory /spark heapsummary use when the server has high memory /spark heapdump use when the server has high memory

if these dont give enough info we have to dig deeper.

Patience I have a job besides working at Headlimiter. All these reports are pretty in depth and I need time to work on it. I will Let you know if I find something

Okay what i think is happening.

Headlimiter checks every chunk if it has x amount of blocks. by checking that its adding its results to a cache in memory. These results are kept till the server shutsdown. The longer the server runs the more chuncks are checked. What i could do is add a period of how long they should stay in the chunk for but that would mean there are more spikes. To add on this though Headlimiter only uses 667KB in memory. Which is nothing. This is not a Headlimiter issue. Also when you ran this your server had 12gb of memory used if you want me to check this properly run. /spark heapdump when its at like 20gb. you can ping me on discord since i will be closing this ticket
