--- Comment #1 from Arjen Hiemstra <ahiems...@heimr.nl> --- CPU usage is calculated by reading `/proc/stat` and subtracting the previous value from the current value. The sudden large value suggests that suddenly the new value is less than the previous value, which would lead to integer overflow like that. Can you run `watch -n 0.5 cat /proc/stat` and see if the values jump back at some point? -- You are receiving this mail because: You are watching all bug changes.
