I am on Ubuntu 20.04 with 64GB RAM and Threadripper 32 Core, when emptying trash, with 32K files (the Flikr 30K dataset), a number of gvfsd-trash threads are spawned and the Gnome desktop freezes.
To determine it was gvfsd-trash, I switched to another tty, logged in to console, and killed the process using htop. This restored desktop functionality. I don't know what to look for in the logs, but I can reliably reproduce the behaviour. Steps: 1. download the flickr 30K dataset : https://www.kaggle.com/hsankesara/flickr-image-dataset 2. Extract and then open the folder containing the files (this will take about 22s in Nautilus on my workstation, as an aside this operation takes >2s in Windows Explorer), 3. Select All (This takes about 9 seconds, as an aside, this operation takes >.5 seconds in Windows Explorer). 4. Delete files (This takes a few minutes) 5. Empty trash and watch Gnome Shell and all applications hang like me?? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1558768 Title: gvfsd-trash causing high CPU-load when try to empty trash with thousands of files Status in gvfs package in Ubuntu: Confirmed Bug description: - Ubuntu 16.04 (Xenial Xerus) Daily Build - AMD64 - Unity Steps to reproduce: - a folder with thousands of files (here about 15000 files with a overall size of 1.5 GB) - delete files to trash - right-click at the trash icon - click empty trash A dialog "Dateioperationen" shows "vorbereiten" (it's German, I think in English the dialog has the title "file operations" and shows the text "prepare"). This happens at this point: - the dialog remains unchanged - the process gvfsd-trash consumes up to 75% CPU, see output of top After 30 minutes of waiting for any reaction I killed the process. The trash still contains all the files. jan@janvm160464:~$ top top - 20:17:24 up 31 min, 1 user, load average: 1,94, 1,97, 1,68 Tasks: 244 gesamt, 5 laufend, 239 schlafend, 0 gestoppt, 0 Zombie %CPU(s): 85,1 be, 14,6 sy, 0,0 ni, 0,0 un, 0,0 wa, 0,0 hi, 0,3 si, 0,0 st KiB Spch : 4037984 gesamt, 2142152 frei, 900784 belegt, 995048 Puff/Cache KiB Swap: 0 gesamt, 0 frei, 0 belegt. 3028940 verfü Spch PID USER PR NI VIRT RES SHR S %CPU %MEM ZEIT+ BEFEHL 1760 jan 20 0 454696 24448 7840 R 69,1 0,6 20:05.18 gvfsd-trash 1690 jan 20 0 781012 71096 36440 S 12,0 1,8 6:13.42 nautilus 2649 jan 20 0 660088 41700 30328 S 10,3 1,0 0:04.29 gedit 315 root 20 0 32236 2936 2500 R 3,3 0,1 1:06.21 systemd-jou+ 825 root 20 0 383184 77448 31492 S 1,3 1,9 0:15.84 Xorg 1543 jan 20 0 1254876 189468 65780 S 1,3 4,7 0:19.38 compiz 641 syslog 20 0 256380 3364 2684 S 1,0 0,1 0:16.81 rsyslogd 1521 jan 20 0 567508 32776 25756 S 0,7 0,8 0:01.16 unity-panel+ 1448 jan 20 0 39728 316 12 S 0,3 0,0 0:00.13 upstart-dbu+ 2258 root 20 0 0 0 0 S 0,3 0,0 0:00.23 kworker/u12+ 2695 jan 20 0 48912 3868 3136 R 0,3 0,1 0:00.01 top 1 root 20 0 119720 5664 3780 S 0,0 0,1 0:02.72 systemd 2 root 20 0 0 0 0 S 0,0 0,0 0:00.00 kthreadd 3 root 20 0 0 0 0 R 0,0 0,0 0:01.45 ksoftirqd/0 5 root 0 -20 0 0 0 S 0,0 0,0 0:00.00 kworker/0:0H 7 root 20 0 0 0 0 R 0,0 0,0 0:06.15 rcu_sched 8 root 20 0 0 0 0 S 0,0 0,0 0:00.00 rcu_bh To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1558768/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
