High resource usage problem. Memory leak

Describe the bug I have the physical server without virtualization and run Aleph via docker compose. Server resources: RAM 512 Gb CPU 128 LVM 10 Tb

I'm trying to add files to the server (near by 40 Gb). After some time the upload process crashes, because the server used all resources. Via top I see the process soffice.bin which uses all my ram.

To Reproduce

Run Aleph via docker compose.
Try to upload different types of data (xls, xlsx, pdf, zip etc.)

Expected behavior The upload process should complete successfully and soffice.bin should not use all server resources.

Aleph version 3.15.0
