java.lang.OutOfMemoryError whenever rejoining a server
Happened thrice now, where I'll delete the .sqlite file for the server, fly around generating lods for awhile, then ill quit out of the game to go do something else, and when i rejoin I load in and the game almost immediately freezes and then crashes.
Here's a screenshot of the log, just in case.

How much RAM do you have in your PC?
How much did you allocate to MC?
And what is the RAM usage in the F3 menu just before the crash?
I have 32gb, I have 16 allocated to the game, and ill open up my resource monitor and check what it looks like as it's crashing rn
alright so on the menu it sits around 8, and then when i join it shoots up to 24, hangs, then crashes
earlier I tried giving it 20gb to play with and it did the same thing but shot up to 28 instead lol
yeah double checked by looking in the F3 menu and not task manager, memory shoots up at an immediate and alarming rate before crashing hahaha
Do you have any custom GC/JVM flags?
the only java arguments ive changed is the amount of ram allocated
Its actually doing it even with rendering turned off for some reason
ok so even with rendering off and all the threading settings set to the default of 2 threads at 0.25, the memory usagage still instantly spikes, just at a mildly slower rate
is there any i should have?
Disabling rendering only hides DH, it still does everything it normally does
When allocating more than 8 GB of RAM it is advise to have GC tuning flags to reduce the stutter.
You can try if these flags fix your problem, but I really doubt they will:
-XX:+UnlockExperimentalVMOptions -XX:+UseZGC -XX:+ZGenerational -XX:+AlwaysPreTouch -XX:+UseFastUnorderedTimeStamps
They require JAVA 21, so for MC <1.21 you will also have to override the JAVA version
.
-XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=40 -XX:G1MaxNewSizePercent=50 -XX:G1HeapRegionSize=16M -XX:G1ReservePercent=15 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=20 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true
Here are more classic GC tuning flags, a bit old at this point, but still good enough for most
.
I've asked as some guides are adding flags that may increase the memory usage in some edge cases
.
What is your full mod list?
/logstoredYou should send your
latest.log file to provide additional useful information.
Logs are located in the .minecraft/logs directory.

Please upload the file to mclo.gs instead of sending the raw file. This makes reading the contents of the file a lot easier and improves the chances of you getting the help needed.
After uploading the file, click on Save and send the link.really mainly performance stuff along with some QoL tweaks
unfortunately they didn't haha, but ill keep them just for the normal stuttering for the future lol
I have no idea what can be causing this
Does this happen when you disable everything except DH?
let me do that rq
:colphneSmile:
this has me goofed man idk lmao
-deleted the (quite large) .sqlite for the server, joined, memory shot up to 99, but then back down to 1% and just sort of hovered around 30%
-left, rejoined, no crash.
-decided to generate just a bit of land to see if that would put it over the limit, only around a couple hundred blocks.
-left, rejoined, crash
why a 40mb sqlite is causing a memory leak and crash is beyond me
what quality preset do you use?
pretty high
but i don't think that explains the 0-99% memory in less than 5 seconds, with next to zero effect on cpu and gpu usage at all
i could be wrong, so ill test it
It shouldn't but I'm running out of ideas, so try mediun preset
The nightly can just have a new bug, that wasn't fixed yet
You can try DH 2.2.x
Or redownload DH 2.3 in case a fix was already added
whats going on the bot is legit like not letting me type
actually blocked like 6 messages in a row
anyways
d word is blocked
:alibaba_wuh:
i dont even think churches disallow that word lmao
ill be gosh darned, but that actually fixed it
ok good "darn" isnt blocked
I turned the vert and horizontal resolution down to the lowest setting and it stopped crashing'
well glad it is working, but IDK why it wasn't
Now you can try finding the highest "safe" settings
ill try reverting to 2.2.x and also redownloading 2.3
very very strange
yeah i have no idea because i have no idea why it was crashing on a 40mb sqlite when previously i had a 3GB sqlite that i had to delete since I got a new drive
no difference in settings
yeah whatever the latest nightly build i had installed just had a [redacted] up memory leak
or had something about it that caused a crazy memory leak, not to put all the blame onto the mod lol
So does DH 2.2.x work corretly?
yeah ive been testing it out, both loading lods and generating new terrain and stuff, everything seems to be working fine
occasionally i get some pretty large holes, but relogging fixes it
That is bad to hear
You are the only one with the problem right now
So I won't ping any devs yet
But there might be a new memory leak or something
16 GB should be plenty
yeah I know with java especially anything past 16 is basically diminishing returns, because java doesn't like using memory efficiently at all
I've been doing testing and even with my render distance set to 300 w/ a 6gb sqlite file, literally no issues at all on 2.2.0
