What's the configuration ( especially the "options" section) ?

If the options sections don't hide any problems i would advize upgrading
to a recent version.  bind-9.2.1 works good with this OS, 

ftp://ftp.sunfreeware.com/pub/freeware/sparc/8/bind-9.2.1-sol8-sparc-local.gz

could be installed as replacement ( you need to tweak your config sligtly 
to make rndc usable )
