[nsp] identifying reason of increasing in router CPU load

[Jing Shen]

Hi,
 
 
We noticed several access switch (Catalyst4006) CPU load increases steadily
in past days, when checking by 'show proc cpu', it shows something including
:
 
PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process
 
153864            17871130       8     0.00%  0.00%  0.00%   0 Per-Second

3269298281067594379        306 32.93% 32.68% 32.55%   0 Cat4k Mgmt LoPri 
   
749292  70964735         10  0.08%  0.00%  0.00%   0 Galios Reschedul 
 
 
But I don't know what's the exact meaning of 'Cat4k Mgmt LoPri' & 'Cat4k
Mgmt HiPri', and we could not identify whether this is just the reason for
CPU load increasing. 
 
Is there anybody could do me a favor to help with this?
