  • process/sleepingBeauties.stp - Generating Backtraces of Threads Waiting for IO Operations
    +subsystems: scheduler, keywords: io scheduler backtrace
    +

    The script monitors the time that threads spend waiting for IO operations (in "D" state) in the wait_for_completion function. If a thread spends over 10ms, its name and backtrace is printed, and later so is the total delay.
