Description

I suggest to enable a limit for image sized which for thumbnail processing.
Tif files can produce a high memory load even if they seem to be small. e.g. a tif file of 104kb has dimensions of 13277x9387px (DIN A0?) which results in memory consumption of >400 MB when processing the thumbnail generation with convert.
I've found these files often in CAD environments, where drawings are converted from CAD to tif.
A workaround is of course to disable tif-preview at all via $TYPO3_CONF_VARS["GFX"][imagefile_ext]

store some tif files in your fileadmin, (attached is a blank one with this large dimensions)
enable thumbnails in the File-Filelist Modul and enjoy watching the process 'convert' grow, e.g. via top
