Hi,

What was the previous IOS version?
These problem was not observed under SXF5 and SRA1 on network I have
worked with.

Regards,
Alaerte

We recently upgraded some of our 7600s/SUP2s to SXF8 and now are seeing
the following error messages at random times.  When these events occur,
the router has CPU issues where it will drop BGP/OSPF sessions due to
hold timers expiring and drop interfaces due to missed keepalives.  The
documentation on the error message points to a possible hardware
problem, but we have seen this on 6 routers thus  
far and it's highly unlikely it's a problem with bad hardware.    
Generally we'll get a few of these in a row and then things  
stabilize.   I've been investigated a link between these events and  
heavy BGP update times, but haven't found any concrete data as of  
yet.   We have opened a TAC case and have thus far gotten nowhere.
