Hi Steve,

On a nut shell, your looking at all the blocked process in the PRP3 and obviously you can run this against every LC.

Some of the processes meant to be blocked while other are not supposed to. Each process has its unique job id, process id and the left column is the thread id. The next column is the process name then the time in its current state. The last column is very important, it tells you what is blocking that process.

Few things that stands out "Mutex", long time in the same state, not necessarily these are wrong but you may want to look further with these.

Although this is C12K, you can benefit from the following document that facilitates the IOS-XR SW architecure(the majority of this doc addresses the entire XR platfrom family while some is more ASR9K oriented):

https://supportforums.cisco.com/docs/DOC-36339

Another doc in CCO which facilatates troubleshooting process and memory:

http://www.cisco.com/en/US/docs/routers/xr12000/software/xr12k_r3.9/system_management/command/reference/yr39xr12k_chapter11.html

Actually, when you open a SR and able to provide that kind of information it will save us both a significant time to identify the root cause and the right course of action to recover.

Enjoy IOS-XR
