Linux Working On A Counter To Keep Track Of The Number Of Hung Tasks Since Boot
Sent out in original patch form this past week and already iterated to a second version this Sunday, a new proposal is underway to introduce 'hung_task_detect_count' as a convenient means of tracking the number of times hung tasks are detected since boot.
Sent out in original patch form this past week and already iterated to a second version this Sunday, a new proposal is underway to introduce "hung_task_detect_count" as a convenient means of tracking the number of times hung tasks are detected since boot. With a set of two patches now under review,/proc/sys/kernel/hung_task_detect_count would be added to report the total number of hung tasks detected since boot time. Once this counter is in place, in a high-density deployment pattern, we plan to set hung_task_timeout_secs to a lower number to improve stability, even though this might result in false positives.
