Image Library Update Halts at 18648 with v1.8

Hi Serviio Friends, I have been using Serviio since v1.3 for streaming my home videos and personal images. With the latest version, v1.8, I noticed that after a new installation (C:\Serviio-180 vs. C:\Serviio-1.7) the library does not update after reaching a total of 18648 images. With versions 1.7 and 1.6.1 the entire library is created successfully. I installed v1.8 over both v1.7 and v1.6.1, where the library already existed, and all the images show up. I had to take a break with troubleshooting for the moment but wanted to post to see if anyone else is running into a similar issue. I updated the JDK and ffmpeg just to keep these updated. If anyone else is seeing a similar behavior and was able to solve it please share. As I mentioned, as workaround is to install v1.8 over a previous version.

Thank you,
