any idea why? This isn't something that happens very often. Do you have
ax25?

The standard solution.

No, it is a known Berkeley DB 1.85 problem. I go to a great deal of
trouble to prevent it but it isn't successful in every case. If the
system locks it is likely that the dupefile is corrupt and should be
removed then the node restarted.

It is aledged that later versions of Berkeley don't have these problems
and since most RPM based things now have DB 3.xx available I may go onto
that.
