That's a seriously broken hash table link.

How do you reproduce it?  Is there a recipe or is it matter of waiting
for a few minutes, hours, or days?

Is NFS or some other network file system involved? 

Do you copy the file or do anything else unusual?  

Can the problem be reproduced with a smaller white list?

There once was a DCC server in the global network running on AIX 4.1.PPC.

"Delayed" means that report will not be immediately flooded to other
DCC servers but a delayed summary will be synthesized and flooded.
