Need help with a crash report

So this crash report came from my production server, it seemingly crashed randomly (not during startup). I have the exact same list (and versions) of all mods on my dev server, and that works well. Server: Fabric 1.21

It would start up, run without issues for some time with people playing, and just crashed seemingly out of nowhere

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

also seeing a lot of this, I don't have the server configured to resume after crash, wondering what that is

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

logs for the repeated startup and stop

If it’s restarting itself you might be looking at an OOM Although ptero can detect some server exits as a crash and restart @𝒟𝑜𝓂𝒾𝓃𝒾𝒸 are you using an ssd or HDD

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

nvme ssd OOM..? whats that? I've checked the smart status of the drive as well, gave me a pass

Skullians•5mo ago

out of memory

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

let me run a spark for 1m

Skullians•5mo ago

what is sync-chunk-writes set to in server.properties

spawn-animals=true
spawn-monsters=true
spawn-npcs=true

interesting why is the memory so low

Set it to false

Skullians•5mo ago

What does ptero say you’re using in terms of ram

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

i dont use ptero 🧌

Skullians•5mo ago

:/ what do you use

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

bare metal and btop

Skullians•5mo ago

You just run in SSH?

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

yah

Skullians•5mo ago

:doom_wojak: Interesting

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

I dont need a gui panel, things are all automated with cron

Skullians•5mo ago

12GB vps ?

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

selfhosting

Skullians•5mo ago

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

should I push xms up to xmx?

Skullians•5mo ago

try it Also feel free to remove AlwaysPreTouch seeing as it preallocates the memory If you could get a spark when players are on that would be great if possible

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

think im the only one that can hop on rn

Skullians•5mo ago

setting sync chunk writes on server.properties might help with your input issue on saving

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

everyone else are sleeping (or offline)

Skullians•5mo ago

AntiXRay seems to have caused an issue

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

okay new startup flags

Skullians•5mo ago

make sure you’re up to date Missing a space between Xms and Xmx

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

it's the newest release from when I checked like a week ago oooh

Skullians•5mo ago

interesting

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

but yes, anti xray have caused issues on my dev server as well, forgot how i dealt with it but it doesnt seem to like the other mods will remove it for now

Skullians•5mo ago

yeah, I would also make a GitHub issue on their page

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

will go do that while the vm reboots

Skullians•5mo ago

sweet

𝒟𝑜𝓂𝒾𝓃𝒾𝒸OP•5mo ago

commited well it started up just fine, will monitor it for a while and see if more crashes happen but thanks for helping let me get one last spark report in

Without any players on a spark doesn’t help much unfortunately
