Server occasionally crashing after using Nether portals
I'm running a Fabric 1.21 server and lately I've been seeing occasional crashes when I rapidly move in and out of Nether portals. Usually it is as mild as a client disconnect, but sometimes it results in the server crashing, and even once it took down the host machine (Unraid running Docker). I'll attach the crashlog of the most recent incident, but I can't make heads or tails of anything in it.
Is there some sort of problematic mod or setting that I may have accidentally enabled?
Thanks.

Please check your server log for errors from your plugins.
If you need further help understanding the errors, please send us the whole log file.
Where can I find the server log?
Logs are stored in
<server_directory>/logs/. Search for a file explorer in your server's management interface and navigate to that directory. Once you've opened that up, search for the latest.log file. Some providers have a separate page for logs and may hide the "logs" folder.
On Aternos:
• Go to https://aternos.org/log/.
On Minehut and server.pro:
• Go to the "files" tab in the left menu.
• Navigate to the root directory of your server.
• From there navigate to /logs/latest.log.
What should I do with the log?
• First of all, read it! I mean, that's what you do all the time when you run a server, isn't it? Try to locate any errors that have anything to do with the issue you are facing.
• If you got the latest.log file or created a .txt file with the necessary errors you can upload these directly to the channel, but we prefer if you upload them to https://mclo.gs/.
• If you have trouble downloading the log file, copy/paste the text to a paste service (like mclogs). Copy the link that it gives you and send it to us. (Don't worry, McLogs hides your users' IPs.)Admincraft Canned Responses

And here is one where I believe I caused a crash
the earlier latest.log isn't necessarily a crash
Have you pregenerated
no, but the portal is to an established area that has already been generated
e.g. not a blind portal

Server Crashes when trying to generate the end/nether · Issue #995 ...
ATM8 1.0.13 Every time myself or other players on the server try to use a nether portal or end portal the server times you out, then crashes. https://mclo.gs/Pssz2Bm
What mods do you have
i'm hesitant to delete our nether as we've put a bit of work in to it, and it's more an issue leaving the nether than entering it
but i could for testing purposes if there wasn't anything more obvious
In the comment I linked it just mentions downloading the nether off your server, enter it in singleplayer, go out and in again, and then re upload it back to the server
Not outright deleting
You can take backups in case something goes wrong
oh i misread that
i'll give it a shot, but i'm not sure it completely applies -- could be an issue with the server not fetching the world files fast enough but i'm not sure what would cause that
What drive are you on?
HDD or SSD
i'll double check my settings, but they should be on an nvme ssd
but that's a good point
if it was on the array that would kill it
set sync chunk writes to false in server.properties
i think it may have been writing to the array
i'll move things over and see if that improves issues
tyvm!
It’s possible however if the area + portal was already generated there wouldn’t be any writing
only reading
i hadn't noticed it was set to spill over onto the array
ah
what does this do?
Setting it to false allows servers to save chunks off the main thread loop
Also iirc relates to HDDs and SSDs
kk thvm
well, moving the files fully on to the nvme ssd seems to have alleviated much of the issue. Thanks for the help troubleshooting!
