I may have stumbled upon a bug or perhaps it's the nature of using a container. I'm also a complete noob when it comes to this stuff. That said, I've managed to mostly successfully install headless YacReaderLibrary Server onto a Qnap system using Qnap's Container Station. Both methods below I was able to get connect locally and remotely to my library (pretty cool stuff)
Method 1 - using muallin/yacreaderlibrary-server-docker.
Method 2 - using the raspberry pi instructions and installing all dependencies on a Debian docker.

With both instances when reading online on an iPad or iPhone when I get to the end of a comic (no more pages), I tap from within the comic as if the next comic were going to open. Subsequently, the server times out and crashes. The console message is: Segmentation fault

Any insight into this crashing would be greatly appreciated...

Yes, that is a bug. Luis will have to take a closer look at it (I don't own any Apple devices, so I can't test it).

No worries - appreciate the reply and glad to know that I didn't screw something up on my end...
