show processes blocked Command
The show processes blocked command displays details about reply, send, and mutex blocked processes.
Since a temporary blocked state for any process is possible, it is recommended to run the show processes
blocked command two times consecutively for each interval and for each node. If a process is displayed
as blocked after the first and second iteration, you can run the command a third time to ensure the process
is blocked.
The polling interval should not be too short (enough to show a sustained blocked state). For example,
the Cisco CRS-1 8-Slot Line Card Chassis requires a minimum of 20 requests for each interval (2 RPs
and 8 LCs) if fully equipped.
The show processes blocked command output always displays processes in the Reply state as blocked.

For these processes it is a normal output. For example, the line:
65770 27726088 1 show_processes Reply 1 kernel
is a direct result of executing the show processes blocked command. Each time the command is applied
the process ID (PID) will change.
If a vital system process or fundamental application controlling connectivity (for example, routing
protocols or Multiprotocol Label Switching Label Distribution Protocol [MPLS LDP]) appears blocked
in the Reply, Sent, Mutex, or Condvar state, do the following:
