weird dns file error

Since a couple of week I have a weird behavior problem on the ispconfig 3 DNS.
Here is the server details:
ISP config 3.0.3.3
Ubuntu os 2.6.32-34-server x86_64

Here is the pri.example.com file when I use the wizard in the dns section:

user@server:/etc/bind$ cat pri.example.com
$TTL 86400
@ IN SOA ns1.domain.com. info.domain.com. (
2011102501 ; serial, todays date + todays serial #
28800 ; refresh, seconds
7200 ; retry, seconds
604800 ; expire, seconds
86400 ) ; minimum, seconds
;

example.com. 86400 A 10.0.0.100
example.com. MX 10 mail.example.com.
example.com. NS ns1.domain.com.
example.com. NS ns2.domain.com.
mail 86400 A 10.0.0.100
www 86400 A 10.0.0.100

user@server:/etc/bind$

Some 86400 number are not in their place. This cause the domain error.
I checked the default creation template but everything seems to be ok.

Any idea of how to fix this?

Spazio.

 

These are optional.

What error message are you getting?

 

The domain stop working. No web, no mail. If I do a dns report on it. Praticly everything exept the NS comes back as fail.
www
mx
etc

Meanwhile I take out the misplaced 86400 number manually and it all comes back ok.

 

Do you get any error messages (also in your logs) when you restart BIND (with the 86400 number)?
