Hey everyone, we had a weird incident where the TPS suddenly crashed to under 10 TPS in basically one minute. We were close to the memory limit, but I'm wondering if anyone else knows whats up here:

I find it kind of bizzare for it to be this way with the specs we have and the player count of 10 :/

running out of memory

most likely a memory leak

Ah, this time an internal one
A spark heapsummary should help then?

Is there like any way to tell where an allocation is coming from?
The tps at a certain point starts dropping
Even if memory isn't full

@Akita hi
could u send a new spark timings/heap report cos the one from before doesn’t work anymore
could u send a new spark timings/heap report cos the one from before doesn’t work anymore
nvm i clicked the wrong one mb
entities/tile entities & chunks seem to spike a lot when u see ur tps drop

pretty sure thats also what's happening here but idk

to me it just looks like theres a lot of entities loaded in ur world and its taking up most of the duration % of the tick
can also see a massive spike in the entity count along with the tile entity count

Thx for the reply
Do you find these numbers to be high?
I don't really have a sense of what exactly is big or not

idk im not an expert either
i was just looking at the graph and gave an observation
lmao
AkitaOP
Makes sense, thanks
Anyway we did another spark report and found 1.8gb of Itemstacks that fills up the memory
So there's definitely a plugin leaking memory
