I was sitting down, browsing reddit, minding my own business, when suddenly I noticed the system is running out of ram. Turns out /usr/lib/udisks2/udisksd has helped itself to 1.7G of memory and was still going at it, at a rate of about 10MB/second. I managed to freeze the process and take a backtrace. I'll attach it in a moment. Before that happened I was playing with app-cdr/cdemu, perhaps that's what triggered a bug. I'll try to reproduce it and let you know if I find something.

Created attachment 338520 [details] udisksd backtrace
It's definitely triggered by cdemu, I killed udisksd and restarted it manually and the console immediately got flooded with this: 16:18:34.732:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.735:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.736:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.736:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.739:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.739:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.739:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.742:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.742:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.743:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.746:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.746:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.746:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.750:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.750:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.750:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.753:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.753:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.753:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.756:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.757:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.757:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.760:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.760:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.760:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.763:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.763:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.763:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.766:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.766:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.766:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] 16:18:34.769:[19948]:[DEBUG]: uevent change /sys/devices/platform/vhba/host10/target10:0:0/10:0:0:0/block/sr1 [udiskslinuxprovider.c:903, udisks_linux_provider_handle_uevent()] 16:18:34.769:[19979]:[INFO]: Cleanup check start [udiskscleanup.c:416, udisks_cleanup_check_in_thread()] 16:18:34.770:[19979]:[INFO]: Cleanup check end [udiskscleanup.c:454, udisks_cleanup_check_in_thread()] ^C16:18:34.771:[19948]:[INFO]: Caught SIGINT.

Ok, I found a way to reproduce it reliably now. Weirdly, it requires using KDE's device notification applet. You're gonna need: app-cdr/cdemu-daemon-2.0.0, app-cdr/cdemu-2.0.0, sys-fs/udisks-2.0.91, KDE 4.10 and some .iso image. As far as I can tell, any valid image will do. 1. make sure cdemu-daemon isn't running 2. $ cdemu load 0 <iso image> 3. KDE should pop up a notification applet saying that a device has been connected. Click the "eject" button on this applet. 4. $ cdemu unload 0 At this point udisksd will start allocating memory very rapidly. If you kill cdemu-daemon it will stop, but will not give back the memory it already allocated. You can now repeat the above steps without restarting the system or even udisksd and it will start leaking again. I tried "ejecting" the device using the 'eject' command instead of KDE's applet, but couldn't reproduce it this way.
I forgot to mention: you also need the vhba kernel module from sys-fs/vhba-20120422-r1.
I've seen this before, according to some people at #systemd, this is because of the vhba kernel module Alexandre, can you take a look as vhba maintainer?
Please test with 2.1.6 Thanks
