Simple strace
SUMMARY
I'm on Debian Testing and since a couple of weeks ago I have a thumbnail.so
process eating 100% cpu whose parent is kdeinit5
the COMMAND, according to ps aux is:
thumbnail.so [kdeinit5] thumbnail
local:/run/user/1000/klauncherbBDJNm.1.slave-socket
local:/run/user/1000/plasmashelllugShP.3.slave-socket
STEPS TO REPRODUCE
I don't know:
I have 5 activities with 1 virtual desktop each.
- I removed all folder widgets
- I configured all layouts to Desktop (not Folder View)
For whatever reason when I switch into my Coding activity, thumbnail.so cpu
goes to 100%. If I kill it it respawns not eating cpu. I leave coding activity,
then return to coding activity and then it starts eating cpu.
If I enable Folder view layout on all desktops then it immediately starts
eating cpu as soon as it respawns.
I cannot find the offending document so you can analize it. I could find it if
you can help me with one of the following:
- How can I list all files and apps favourited to a certain activity?
- How can I see in a config file all widgets associated to an activity? (Since
many times the updates messed up badly on my widgets, I fear I may have an off
screen or 1pixel size widget)
Also, I did an sudo strace -s 180 -p <pid> to it and I found it is on an
infinite loop. I attach the file.
Maybe it is easy to solve with the trace I'm providing. It is definetly
something that landed on Debian a couple of weeks ago.
