Always the same wrong cache entry

[Robert Meixner]

I have a primary (dns1.netway.at) and a secondary (dns2.netway.at)
nameserver both running bind 8.2.1. They both cache an invalid A record.

# nslookup bmuknt02.bmuk.gv.at dns1.netway.at
Server:  dns1.netway.at
Address:  195.96.0.1

Non-authoritative answer:
Name:    bmuknt02.bmuk.gv.at
Address:  193.171.130.20

# nslookup bmuknt02.bmuk.gv.at dns2.netway.at
Server:  dns2.netway.at
Address:  195.96.0.2

Non-authoritative answer:
Name:    bmuknt02.bmuk.gv.at
Address:  193.171.130.20

If I query the primary and secondary DNS for the domain bmuk.gv.at I
receive a different answer.

# nslookup -type=ns bmuk.gv.at ns1.univie.ac.at
Server:  ns1.univie.ac.at
Address:  193.171.255.2

bmuk.gv.at      nameserver = ns1.univie.ac.at
bmuk.gv.at      nameserver = ns1.bmuk.gv.at
ns1.univie.ac.at        internet address = 193.171.255.2
ns1.bmuk.gv.at  internet address = 193.171.130.20

# nslookup bmuknt02.bmuk.gv.at ns1.bmuk.gv.at
Server:  ns1.bmuk.gv.at
Address:  193.171.130.20

Name:    bmuknt02.bmuk.gv.at
Address:  193.171.130.23

# nslookup bmuknt02.bmuk.gv.at ns1.univie.ac.at

The zone file for the domain bmuk.gv.at seems to be alright.

Even if I stop and start bind on dns1.netway.at I get the wrong address
for bmuknt02.bmuk.gv.at. On dns2.netway.at the bahvior is more strange.
After stopping ansd starting of named I can get thet corrct answer.
After the timeout of the entry (TTL) I get the wrong answer for
bmuknt02.bmuk.gv.at and also a different TTL for the entry.

After starting/stopping the named.

# nslookup bmuknt02.bmuk.gv.at dns2.netway.at
Server:  dns2.netway.at
Address:  195.96.0.2

Non-authoritative answer:
Name:    bmuknt02.bmuk.gv.at
Address:  193.171.130.23

After the cache entry has been expired (TTL).

# nslookup bmuknt02.bmuk.gv.at dns2.netway.at
Server:  dns2.netway.at
Address:  195.96.0.2

Non-authoritative answer:
Name:    bmuknt02.bmuk.gv.at
Address:  193.171.130.20

What can be wrong?

Kind regards,
