Memory leak when reaching the last page of a PDF book

[francoishernandez]

Steps to reproduce

1. Open a book (in my case a PDF magazine) in reading mode (tested with Chrome browser)
2. Move to the last page
3. Press the right arrow key when on last page
4. Memory is shooting up and the JVM is not happy (it's stuck, I need to manually restart the docker container)

Expected behavior

Not exactly sure what is happening. There should probably some form of safeguard to prevent this behaviour. Or prevent moving past the last page.

Actual behavior

Memory usage is shooting up, saturating the allocated JVM memory.

Komga version

Operating system

Ubuntu 24.04 w. docker

Installation method

Docker

Other details

I have seen various discussions around memory usage. I don't think that's the same issue here, as there seems to be a bug with the reader when reaching beyond the last page of a book.

How big is the PDF ?

The JVM is running out of heap space: java.lang.OutOfMemoryError: Java heap space

Did you set any environment variable to limit the JVM memory ?

How big is the PDF ?

Does not seem really relevant here, I reproduce with PDFs of various size, from ~20MB to ~100MB.

Did you set any environment variable to limit the JVM memory ?

Nope, it seems to default to the standard 4GB.

It seems that whenever we reach the end of a PDF, and go to the next one (keep pressing the right arrow), it happens. Don't you reproduce?

I just reproduced with another random PDF picked in my library.

I can't reproduce.
