Do you have Dynamic Update defined for the zone? If so, then the only 
safe ways to maintain the zone are through Dynamic Update itself (e.g. 
the nsupdate command) or by freezing and thawing the zone (you'll need 
to upgrade to BIND 9 for that, and bear in mind that while the zone is 
frozen, you'll lose any interim Dynamic Updates, so I don't know that 
this can be truly considered "safe"). Combining Dynamic Update with 
manual edits and no freezing/thawing is a recipe for zonefile corruption.
