The coredump seems to be just various things starting to go wrong in packagekitd when we start running out of resources and I don't think there's much we can do there, HOWEVER: The main issue seems to be that we're starting gnome-software on the live media, which in turn is starting packagekitd and asking it to download metadata. This is 100 MB download which eats up precious RAM as the file system overlay on the live media is backed by memory. This all adds up with gnome-software using RAM, packagekitd using RAM, and downloaded metadata using RAM. Working on fixing it now to avoid all that on live media. -- Kalev _______________________________________________ desktop mailing list -- desktop@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to desktop-leave@xxxxxxxxxxxxxxxxxxxxxxx
