ASR 1002 LSMPI_IO @ 99.98% constant usage---meaning, concern?

Our ASR 1002s, running Cisco IOS Software, IOS-XE Software (PPC_LINUX_IOSD-ADVIPSERVICESK9-M), Version 12.2(33)XNF2, RELEASE SOFTWARE (fc1) are showing Memory Utilization in CiscoWorks 4.0.1 of: 

Instance Name Min (%) Avg (%) Max (%) Graph
1.lsmpi_io99.9899.9899.98

  (graph omitted-----flatlined @ 100% constantly)

While increased documentation about this usage is available, I still cannot find clear information if this is a problem or not.  Thanks for any link, reference, or information you can provide.

This is normal behavior for the ASR1000 due to the architecture.

This pool is unique to IOSd and is a shared memory region between the Linux kernel and the IOSd process. On most platforms running IOS the buffers in the show buffers output are allocated from the I/O pool and can grow dynamically. On the ASR1000 most of the buffers are allocated from the processor pool. This same information is in CSCso50946 and https://supportforums.cisco.com/docs/DOC-16425
