Hi Liudmilla, think it should read "Tiling failed for module ...".
Tiling is a process where darktable splits the image in rectangular tile and process them one after the other and recombining the full image in the end. This is done in order to save memory and is especially needed if you are short in RAM or if your are on a 32-bit system. The problem now is that - depending on the module and its settings - darktable needs to process part of the tile as an "overlap" area to avoid borderline artifacts. That overlap area is not used when recombining the tiles. For the shadows and highlights module this needed overlap area depends on the blur radius and can get very large. Suppose that your memory situation requires the image to be processed in tiles of 400 x 400 pixels. If the overlap area needs to be 200 pixels (on each of the four sides of the tile) it's clear what happens: there is nothing left "in" the tile which can be used. What darktable does in that case is to forget about tiling and just tries to push through the image in one chunk. That might give all possible results: it sometimes works, sometimes part of the image is garbled, sometimes darktable crashes. The warning tells you to have a close look at your output if you got what you want. What can you do? You can of course reduce the blur radius in shadows and highlights, but that influences the look of the image. You can increase the configuration parameter "host memory limit for tiling" but that might not work if your system is limited in memory (see above). In general it's strongly advised to run darktable on a 64-bit system with enough RAM (like 4GB or more).
