I was troubleshooting an issue with one static dns entry which is no longer there, but the cache thinks it still is
The cache entry
Name piboven.domain.com
Type A
Data 192.168.110.72
TTL 1d 00:00:00
The static entry
Enabled Yes
Name piboven.domain.com
Address 192.168.140.146
TTL 1d 00:00:00
Clear Cache does not solve this issue and I think this is a BUG
