To further qualify the source of the problem we need to look at each and every NI.

Looking at the health statistics of each NI would give an idea about which one is causing the problem. 
Following CLI command can be used to diagnose:

Show health <slot number> 

Example:

-> show health 5
* - current value exceeds threshold

Slot  05

The NI Debugger software can be launched in Dshell using the following command:

Working: [dshell]-> <nidebug

This will launch the NI Debugger. To change to a specific slot and slice (Coronado) the following 
command can be used:

changeSlot slot,slice

Now the processor on that slot can be accessed just like CMM to see all tasks (running or suspended), 
tasks consuming the CPU the most, and other commands like task trace (tt) or task info (ti).
