Description
Hi,
qtlicd is started when I e.g. run QtCreator.
Even after closing QtCreator, it continuously uses way too much CPU (4,9%) for its task:
1730 <username> 20 0 341512 11336 8368 S 4,9 0,0 36:13.33 qtlicd
It should be idle.
Running strace on it shows only:
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=0, tv_nsec=10000000}, 0x7fda33f9c590) = 0
So the CPU usage is related to its wakeup 100 times a second. That seems kinda excessive, doesn't it?
