Hi Lars,

4.1.15 refuses to load illegally large serial numbers.  This number is
then larger than the 32bits that we have to store it in.  Older NSD
would not actually store that number.  And in 4.1.15 we fixed it that
impossible numbers are not parsed.

201702270932  is too large, your serial number.
4000000000 - that is 4 billion.

usually people have year+month+day+counterfrom1to100.
there is no space for year+month+day+hour+minute.

I have changed the code to print:
error: home.mydomain.org.zone:8: serial is expected or serial too big

Best regards, Wouter
