[GTALUG] Cache DNS issues.

[William Muriithi]

‎Morning, 

I have cache dns running on a postfix based mail server. The bin‎d server do come up before postfix, but dns queries fail till the dns master come up.

Doesn't slave servers keep data persistent? I mean, is it normal for slave to fail resolving queries on start up if the master us down?

Thanks in advance ‎
