MC-249431The server occasionally fails to save chunks
The Bug:
The "Failed to save chunk" error is sometimes logged in the server console, thus indicating that the server occasionally fails to save chunks.
This issue was not present in 1.18.2 or 22w11a.
The following message was printed into the server console shortly after teleporting a far distance away and then running the "/kill" command. The full server log has also been attached which can be found below.

Steps to Reproduce:
- Start a server running 22w12a.
- Teleport a far distance away and then run the "/kill" command in order to make some chunks unload.
/tp @s ~10000 ~ ~
/kill @s
- Respawn and watch the server console closely.
- Take note as to whether or not the server occasionally fails to save chunks.
Observed Behavior:
The server fails to save chunks.
Expected Behavior:
The server would not fail to save chunks.

- Start a server running 22w12a.
- Teleport a far distance away and then run the "/kill" command in order to make some chunks unload.
- Respawn and watch the server console closely.
- Take note as to whether or not the server occasionally fails to save chunks.
Observed Behavior:
The server fails to save chunks.
Expected Behavior:
The server would not fail to save chunks.

Hello [Mod] Avoma, I couldn't find a way to reproduce the issue so far.
Did this by any chance occur together with MC-249431 or an other chunk saving issue?
Some of the reasons for MC-218739 were chunks not saving properly, it could still be a similar cause.
Are there any warnings or errors in the log when it happens?
Also do you know if it can happen the first time chunks are loaded, or does it appear in worlds after moving around and loading/unloading the chunks?
Hi [Mojang] Panda, thanks for your response.
Nope, I can confidently say that this issue didn't occur together with MC-249431 as that was fixed in 22w13a, and I'm still able to reproduce this same problem (MC-249508) in 22w15a, however, I'm unsure if this occurred alongside any other chunk saving issues, so I apologize in advance about this.
I've just tested this now using a vanilla instance of 22w15a with a completely new generated world and was able to reproduce this. At the time of when I did so, no errors or warnings were printed into the game output console and in my testing, this appeared to happen the first time chunks were loaded. Unloading and reloading the chunks where this issue was present in didn't appear to change anything and the lighting error still occurred.
Below is some information on where I experienced this in 22w15a. I've also attached an additional video along with a screenshot. Please let me know if you require any additional details and/or information regarding this problem and I'll do my best to supply you with it. 
Thanks!
Version: 22w15a

According to
MC-249444, it looks like this is also a chunk corruption bug, not just a logspam issue.Thank you, I've updated this ticket accordingly.
This issue may have been fixed in 22w13a, although I'm not entirely sure so please don't take my word for it. After playing on a server running 22w13a for multiple hours and whilst exploring numerous amount of chunks during this time, this error was never logged in the server console.
Can confirm, this has been fixed in 22w13a.
I thought it might have been; thank you!
This bug still affects me on 1.21
