named high cpu usage

[DjiXas]

It's been 2-3 days now when named started to use more cpu than usual. Techs "refuse" to work with that issue and saying that its's normal. Though all the time had no problems, haven't added hundreds of domains yesterday and there were no changes from my end.

Never noticed named before. Mysql was always in top by usage with 4% (top command). Now it says 7% for named.

There was one change from techs side however.

"the MX record for the domain was going to localhost, rather than the domain name. I have changed the MX record to domain..."

Anything I should check? Logs doesn't provide anything valuable, just notices.

Fixed.

Mail dns entry had a name - hostname, so I changed it to c name - domain name.
