I use a Dell XPS 8930 with Windows 11 Pro; Intel(R) Core(TM) i7-9700 CPU @ 3.00GHz 3.00 GHz; 64 GB RAM. It all is up-to-date with latest Gates' imposed downloads.

Fascinating! Almost identical to mine (i7-8700, and 16GB of RAM). I keep wondering when it's going to do something truly ugly, since it's over six years old. But other than a bad Ethernet port on the motherboard, it seems reasonably happy. But I'd dearly love to ditch the monster tower for a micro form-factor machine.

When you go into the preference settings in jAlbum, what's the maximum value for Number of threads? Your CPU is an 8-core, but with single threading, so the max value should be 8. My slightly older i7-8700 is a 6-core, but with dual threading, so it maxes out at 12.

I wonder if it could actually be a combination of changes or even just Tiger. Tiger’s, the last update was to version 5.11.3 on Jul 31 whilst jAlbum was June 23. Always suspicious of odd things happening around changes to code. Just a thought.

If you've got Tiger 5.11.3 (the latest), jAlbum would use that no matter what version of the core you're using. That latest update is sitting in your own config directory, and would be newer than whatever version was bundled with the core, so it would use that newer one every time.

Of course, our focus on web locations could be a red herring. Unless the "problem" projects have nothing else in them, it could be something else that's lurking in there.

First, sorry for this tardy response to the latest posts about my problem. My computer locked up (*not* because of jAlbum) and I had to reboot. As I had set up memory check for my next restart, I decided to let it run rather than abort it. It ran for several hours (64 gigs of RAM) and then we had a really bad thunderstorm that knocked out the Internet service for several hours until around 10:00 p.m.

As an aside, I never found the RAM check results message, but when I had last looked, it was on pass 2 of 2 with total check at 68 percent and it had not found any issues up to that time.

In the meantime, I had set number of threads in jAlbum to 4 and before my crash I had begun a very large test album with ONLY Web location links. Around 9:30 p.m. last evening I tried to Make (compile) it. There were 114 such links. It compiled in under a minute. Sooooooo, for now I think I will keep threads at 4 and when I update albums where I have had the most problems, I'll see see how it goes and report back.

My next test will be a mix of folders with photos and the large number of Web link locations.

I have been meaning to post that all is well with my new threads setting. Thank you for all the advice. Extremely large albums are compiling in a very short time.
