246 | This option controls the default timeout (in seconds) used | ||
247 | to determine when a task has become non-responsive and should | ||
248 | be considered hung. | ||
249 | |||
250 | It can be adjusted at runtime via the kernel.hung_task_timeout | ||
251 | sysctl or by writing a value to /proc/sys/kernel/hung_task_timeout. | ||
252 | |||
253 | A timeout of 0 disables the check. The default is two minutes. | ||
254 | Keeping the default should be fine in most cases. | ||
