Server encounters an unexpected exception and won't boot

When I try booting the server, it says

Server thread/INFO Ensuring rules file exists at path: ./config/essentialcommands/rules.txt

Server thread/INFO Ensuring rules file exists at path: ./config/essentialcommands/rules.txt

Server thread/INFO Ensuring rules file exists at path: ./config/essentialcommands/rules.txt

Server thread/INFO Ensuring rules file exists at path: ./config/essentialcommands/rules.txt

then hangs for about a minute before spitting out:

Server thread/ERROR Encountered an unexpected exception
INFO java.lang.OutOfMemoryError: Java heap space

Server thread/ERROR Encountered an unexpected exception
INFO java.lang.OutOfMemoryError: Java heap space

Server thread/ERROR Encountered an unexpected exception
INFO java.lang.OutOfMemoryError: Java heap space

Server thread/ERROR Encountered an unexpected exception
INFO java.lang.OutOfMemoryError: Java heap space

and the rest of the crash report.
Any idea where I should start looking for the problem?

Please use a paste service instead!

Paste services are more mobile friendly and easier to read than just posting a log file

My server is using too much memory

My panel says my memory usage is high all the time.

Your server runs in the Java Virtual Machine (JVM), which has significant overhead & tries to effectively use ALL of the memory assigned to it.
Memory usage from "htop", Task Manager, or your server panel is the total consumption of the JVM, not just your server.

My server is lagging & I think it's memory related.

It's much more likely that you are bottlenecked by your CPU, disk, or some inefficient mod/plugin.
Rule of thumb, servers should have anywhere from 4GB to 12GB of memory, with 8GB being the 'sweet spot'.
If you're heavily modded, add 4GB to that.
Too much memory can be a bad thing. Don't exceed these caps unless you really know why you're doing it.

Troubleshoot your server the right way: use Spark & send us a report.

My server is randomly terminated unexpectedly.

Setting your server to use 8GB does not mean that Java won't exceed this amount.
As a rule of thumb, allow your system/container about 1-2GB (possibly more) overhead outside of the server.
If you're on Linux & can SSH into the system, check your kernel logs. They will report any incidents of OOM.

I want to use swap to allocate more memory.

Don't. Swap is not free memory and using it can negatively impact performance.

Why would it be actually out of memory randomly on bootup when it wasn't before?

ye, it's worked for me so far, but I'm having my doubts

Deleted User•8/18/23, 5:30 PM

well, try your luck by contacting them

Deleted User•8/18/23, 5:30 PM

better yet, pay more money and get more ram!

HappyPorcupineOP•8/18/23, 5:30 PM

lol, I'll look into that

HappyPorcupineOP•8/18/23, 5:30 PM

strange that it's an issue all of a sudden though

HappyPorcupineOP•8/18/23, 5:31 PM

and on bootup

Deleted User•8/18/23, 5:31 PM

literally though, prices are garbage and support is garbage too

HHappyPorcupine strange that it's an issue all of a sudden though

Deleted User•8/18/23, 5:31 PM

maybe you added new resource intensive mods

Deleted User•8/18/23, 5:31 PM

and uhh it seems to me you're running some kind of hybrid?

Deleted User•8/18/23, 5:32 PM

there's no way placeholderapi works on fabric

Discount Milk•8/18/23, 5:32 PM

How much ram are you paying for?

HappyPorcupineOP•8/18/23, 5:33 PM

8Gb

Discount Milk•8/18/23, 5:33 PM

What's the contents of that "rules.txt" file?

HappyPorcupineOP•8/18/23, 5:33 PM

This is what it looks like when trying to boot up.

Discount Milk•8/18/23, 5:33 PM

Does it exist? Could you send full latest.log? https://mclo.gs/

Is that a copy paste from latest.log? Looks like from the console instead

Discount Milk•8/18/23, 5:45 PM

Okay. What I'd do is try and rename the essentialscommands folder

Discount Milk•8/18/23, 5:45 PM

To like essentialscommands.old

HappyPorcupineOP•8/18/23, 5:46 PM

I'll give that a shot

HappyPorcupineOP•8/18/23, 5:48 PM

Nope, same thing. It recreates the blank rules.txt file and the server hangs for a minute until it gives up

Discount Milk•8/18/23, 5:49 PM

Huh.

Discount Milk•8/18/23, 5:49 PM

!binsearch

Carl-bot•8/18/23, 5:49 PM

Binary search your plugins

Remove half of your non-essential (ie not things like PAPI or LuckPerm) plugins and see if the problem is fixed.
If it still persists, the cause is in the half still installed.
Continue to halve the remaining plugins until you've narrowed it down to a single plugin.
Congratulations, you found the culprit.

One of your mods is getting stuck loading I think.

Discount Milk•8/18/23, 5:49 PM

Forge has a debug file, idk if fabric does.

Discount Milk•8/18/23, 5:49 PM

But binsearch is next bet

HappyPorcupineOP•8/18/23, 5:50 PM

K, I'll start slashing

HappyPorcupineOP•8/18/23, 6:37 PM

looks like the issue was FLAN (https://www.curseforge.com/minecraft/mc-mods/flan/files/4686793)
There was an issue where "entityPermission wrongly parsed causing extreme large files on reload". This made my flan.config file 3.6GB. I had to delete it, but hopefully the issue is fixed now.
