I have a similar problem, again with the 7200 series.
However, it seems to only exhibit itself on the 7200 VXR, NPE200,
series... so far TAC seems at a loss.
OC3 A3-MM cards, and 7204 VXR's don't seem to get along.
UIt exhibits a wedged OC3 Interface, at random intervals...
TAC can offer no safe avenue of code.
Anyone have anything limping along ?
Tried to date:
12.0.3T (As distributed)
12.0.7T
12.0.9S,
12.0.9 (As per TAC, doens't even support the controller)
12.0.13 (Same as above)
12.0.13S (Limping along, wedging every 12-13 hours, or so.
This system is stripped down, and static routing. I have similar
builds on 06's, and am not experiencing this type of issue.
Suggestions ?
