If the error shows up it could be gone a minutes later.

A test case: https://mprove.de/chrono?q=66.08027,21.39488&z=12.21&r=5&t=22&m=IAarkivkopiase-ekonom-J133-25l8a51&d=1 If the map does disappear after a smaller version has been loaded for the fraction of a second, press key D to switch dark mode to reload the image. Sometimes this helps. Sometimes not.

Uploaded a jpg to the IA yesterday of 10500 x 7350 pixels: https://archive.org/details/lametrobikemap Then tried the IIIF service which seemed to work well right away but then started throwing the following errors for tile fetches:

500 Internal Server Error Java heap space java.lang.OutOfMemoryError: Java heap space

Another issue with this one:

it looks like the IA IIIF image server is out of memory? https://iiif.archive.org/image/iiif/2/reportoftreasure00carn%2freportoftreasure00carn[…]p2%2freportoftreasure00carn_0000.jp2/full/full/0/default.jpg
