Does 3.4.x do something different regarding caches / databases than 3.6?
I don't show folders.db, etc... as memory mapped for my running 3.6
[fuser will tell you if an open file is memory mapped or not].
The only memory mapped 'data' files I see are:
/home/awilliam/.local/share/gvfs-metadata/home-897372f8.log (deleted)
/home/awilliam/.local/share/gvfs-metadata/home (deleted)
/home/awilliam/.local/share/mime/mime.cache
/home/awilliam/.config/dconf/user (deleted)
/usr/share/icons/gnome/icon-theme.cache
/var/cache/fontconfig/7ef2298fde41cc6eeb7af42e48b7d293-x86_64.cache-3
/usr/share/mime/mime.cache
/usr/lib64/gconv/gconv-modules.cache
... and a few font files?
See /proc/{evolutionPID}/maps
Will a backtrace record a SIG-BUS? I don't know that I've ever had to
deal with a memory-map issue outside of a straight-up bug.
