[c-nsp] GEIP+ high CPU

[M.Palis]

     Hello all
 We are facing a high CPU utilization on a GEIP+ (avarage 80-90%). Below is 
the output of the show interface and sh contr vip 1 proc cpu which does not 
show which process causes the high CPU and why.  I enable cache flow to see 
the type of traffic that passes through the GEIP+ but it seems that traffic 
is normal.

Can you suggest something that will figure out what is the cause of high CPU 
utilization?
