Note sure whether this is a bug related to rtkit-daemon. I've found the possible culprit (which also explains that I had no problems before): xpdf takes several GB, even though the PDF file is rather simple (26 slides, no images...). The consequence is that the machine is swapping. I suspect a memory leak, possibly when the PDF file is reloaded (I've been writing slides, thus with many reloads...). -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
