What could be the problem?

Big file upload problem.

Below is the listing from the console.

My computer:

-------------------

CPU: 4 cores

RAM: 8G

OS: Linux

BaseX: 107 and BaseX108-20230816.163639

Java: Adoptium idk-17.0.8+7

I'm creating files:

dd if=/dev/random of=file_512M bs=1M count=512

…………………………file_530M

…………………………file_1G

…………………………file_2G

and etc.

Launching “basexhttp" ( default ...-Xmx2g … )

Let's go in … http://192.168.1.120:8080/dba/files

Downloading files - no problem.

Uploading: file 512MB size - no problem.

Uploading file 530MB and more - PROBLEM ( looking console output below )

OK, relaunching basexhttp whith -Xmx4G …..

Uploading file 512MB - ok

Uploading file 1GB - ok

More size - crashes

What could be the problem?

Thank you very much.

Dmitriy Gorskiy.
