1. Every few days I need to reset my Jetty 9 PlantUML service (on Debian), as the server starts hanging and will not load any UML diagram with an <img:path> line.
2. The images are on the server itself and accessed via local file path. However, if I put the path of a non-existent image, the diagram will load showing image not found error where the image should be. I can also get the /uml/ of the diagram, but /svg/ won't load.
3. Once I restart the service, all starts working again, and I can't figure out what is causing the issue.
4. Same problem exists for URL images.
Any suggestions are much appreciated!
