what I call "in use" is like interacting with it rather than letting it "sit there"
the ubuntu-bug collecting job added that list to the bug: https://launchpadlibrarian.net/85141332/usr_lib_nautilus.txt which is the packages you have installed which add a .so to the nautilus directory so that seems to not be coherent with your comments... to reply to your other question, no, leaks are not especially a nautilus bug, they can be due to third party softwares which install some .so loaded by nautilus, leaks in those would show in the nautilus process since that's where they are loaded, the 3 packages listed in comment #6 do install a such .so and could be causing the issue (the other ones in the list of the file I listed as well but those are installed by default and would affect all users where your issue is not something most users notice) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/890441 Title: nautilus memory leak Status in “nautilus” package in Ubuntu: Incomplete Bug description: There are other bug reports with this description, but they are either 3-4 years old, or closed, or invalid, or expired. I'm not doing anything exotic, but after about an hour or two of using my system (not even copying or moving files, or thumbnailing, or...) memory usage in nautilus goes up to 1.4G or so. When I kill this task, re-launch nautilus, it sits happily on just a few hundred meg... and then begins to grow again. It also takes a LONG time to start up, and the system is very unresponsive meanwhile... like 20 seconds. This may be a useful clue? I tried to do a valgrind report, but it makes nautilus so slow as to be unusable -- like 2 minutes to open a folder on the desktop... so I couldn't exactly "use it normally" to get a good log. Nonetheless, here's a log I did capture. I trust that the data captured by ubuntu-bug will have my library versions, cpu type, RAM info, etc. Please let me know what else I can provide. Thanks!
