It might but it would be nothing to do with DNS.

If you say what domains you host we might give advice on the TTL
settings for DNS records, which might be your problem.

Is "top" showing named as the process eating the CPU?

Is it Solaris? Is it logging anything in the syslog, or where
ever named is logging?
