After some time this goes up to 200% (in one step), so using 2 cores. Thread view shows CPU time of CMD 'pool': # ps -T -p <pid-of-udisksd> PID SPID TTY TIME CMD 26229 26229 ? 00:00:00 udisksd 26229 26230 ? 00:00:00 gmain 26229 26232 ? 00:00:00 gdbus 26229 26233 ? 00:00:00 probing-thread 26229 26234 ? 00:00:00 cleanup 26229 3325 ? 00:33:16 pool 26229 5027 ? 00:03:00 pool My solution is to kill it and let it restart. Strace needs to follow threads to show activity, it's then flooding with: # strace -p <udisksd-pid> -f [pid 3325] poll([{fd=12, events=POLLIN}, {fd=17, events=POLLOUT}, {fd=18, events=POLLIN}, {fd=20, events=POLLIN}], 4, 0) = 2 ([{fd=12, revents=POLLIN}, {fd=17, revents=POLLOUT}]) [pid 3325] read(12, "\2\0\0\0\0\0\0\0", 16) = 8 [pid 3325] write(12, "\1\0\0\0\0\0\0\0", 8) = 8 [pid 3325] write(2, "\n(udisksd:26229): GLib-WARNING *"..., 87) = 87 [pid 3325] write(12, "\1\0\0\0\0\0\0\0", 8) = 8 [pid 3325] poll([{fd=12, events=POLLIN}, {fd=17, events=POLLOUT}, {fd=18, events=POLLIN}, {fd=20, events=POLLIN}], 4, 0) = 2 ([{fd=12, revents=POLLIN}, {fd=17, revents=POLLOUT}]) [pid 3325] read(12, "\2\0\0\0\0\0\0\0", 16) = 8 [pid 3325] write(12, "\1\0\0\0\0\0\0\0", 8) = 8 [pid 3325] write(2, "\n(udisksd:26229): GLib-WARNING *"..., 87) = 87 [pid 3325] write(12, "\1\0\0\0\0\0\0\0", 8) = 8 [pid 3325] poll([{fd=12, events=POLLIN}, {fd=17, events=POLLOUT}, {fd=18, events=POLLIN}, {fd=20, events=POLLIN}], 4, 0) = 2 ([{fd=12, revents=POLLIN}, {fd=17, revents=POLLOUT}]) [pid 3325] read(12, "\2\0\0\0\0\0\0\0", 16) = 8 [pid 3325] write(12, "\1\0\0\0\0\0\0\0", 8) = 8 [pid 3325] write(2, "\n(udisksd:26229): GLib-WARNING *"..., 87) = 87 [pid 3325] write(12, "\1\0\0\0\0\0\0\0", 8) = 8 [pid 3325] poll([{fd=12, events=POLLIN}, {fd=17, events=POLLOUT}, {fd=18, events=POLLIN}, {fd=20, events=POLLIN}], 4, 0) = 2^CProcess 26229 detached THANKS!
