You cannot "rebuild" the diff file. Its the changes your received via axfr/notify.
You need to regularly run "nsd patch" to write the diffs back into their zone files.

Then you could automate removing corrupted diffs, though one might still prefer
to know this over automatically fixing and perhaps losing changes to the zones.
