Afte noone could gave me a help I  found a solution for myself.
In icecast chroot mode the resolving/nscd does not work.
Also not, if the libresolv is copied to the icecast chroot.
(dunno if this is a chroot problem or if it is a problem/feature in
combination with gresecurity kernel patches which i use)

If I put hosts in icecastroot/etc and write into that hosts file my yp
hostnames it works fine.
I announce on xiph and oddsock so I created the following "hosts" file in
the chrooted etc dir: dir.xiph.org www.oddsock.org

Good luck
