what causes flushes?

This rural ISP is having problems described below; any help would be appreciated.

Configuration: cisco 7206VXR (NPE300) processor with 229376K/65536K bytes of memory IOS (tm) 7200 Software (C7200-K4P-M), Version 12.0(32)S6, RELEASE SOFTWARE (fc3)

she-gw#show process cpu | incl utilization CPU utilization for five seconds: 68%/46%; one minute: 67%; five minutes: 66%

Issue: poor Miranda

results from customer's viewpoint, including lower downstream rates than upstream rates; typically 3% of packets dropped when unix host pings unix host on another router interface.

1st question: should we be concerned about the number of flushes below?

kind regards/ldv
