LocalPool: Full size is 0, remaining: 1024

In DMA queues: 0
value = 6 = 0x6
The above display of the command does not show the Full size of any of the pools. This indicates that
CMM is unable to view the IPC pools of the NI. In this scenario, one needs to load the NI Debugger and
go to the NI and look at the IPC Pools. One of the NI would be generating many IPC messages that would
result in IPC sockets to be eaten up by that NI resulting in flooding of enormous amount of IPC messages
and in turn loosing communication with the CMM.
The following is an example of using the NiDebug command to display the IPC pools of all NIs.
