undo monitor kernel deadloop time [ slot slot-number ]
In IRF mode:
monitor kernel deadloop time interval [ chassis chassis-number slot slot-number ]
undo monitor kernel deadloop time [ chassis chassis-number slot slot-number ]

Parameters
time interval: Specifies the interval for identifying a kernel thread deadloop, in the range of 1 to 65535
seconds.
slot slot-number: Specifies an MPU by its slot number. If you do not specify this option, the active MPU is
specified. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies an MPU on an IRF member device. If you do not
specify this option, the global active MPU is specified. (In IRF mode.)
Usage guidelines
If a kernel thread runs for the specified interval, kernel thread deadloop detection considers that a
deadloop has occurred. The system records the deadloop and restarts.
Inappropriate use of this command can cause service problems or system breakdown. Make sure you
understand the impact of this command on your network before you use it.
Examples
# Set the interval for identifying a kernel thread deadloop to 8 seconds.
<Sysname> system-view
[Sysname] monitor kernel deadloop time 8
