DNS Corruption

[manlius.com]

In the last 2 weeks we have had the following happen with DNS, it is strange and wondering if anyone has any insite:

Box4 and 7:
4 is master and 7 is slave, 4 becomes corrupt making all the A records for every domain blank. this replicates to 7. all dns zone files need to be rebuilt (thanks to the Rebuild Named Zones Script from cPlicensing.net) and the named.conf regenerated. (this has happened twice now)

Box 6: same issue as on box 4

Box 5: named.conf became corrupt and fixed it by running /scripts/unslavenamedconf (not sure if we nipped this one in the bud from becoming like the others or not)


Any clues what may be causing this?

We had corruption of all our zones 24 hours ago. We had to hit edit & save so they would work again. Bind is really becoming a pain in the arse

Hi,

Today, one of the zone file became corrupted suddenly... What is exactly the problem causing this and how to avoid such thing in future?
