System - No Hung Tasks

Description

There shall be no 'blocked for more than xxx seconds' in dmesg

Check Script: system-hung-tasks.sh

#!/bin/bash

# solution: Solution often depends on the application blocked, rarely on the HW. Clear dmesg buffer to acknowledge.

logged=$(/bin/dmesg | grep 'blocked for more than [0-9]* seconds' | tail -10) if [ "$logged" == "" ]; then result_ok else result_warning "$logged" fi
