DNS Serial Issue in 9.x

[Maciej Wojcikowski]

I encountered an issue with DNS serial not changing after adding a subdomain as a DOMAIN in PLESK. There is a problem, because I use secondary servers which don't know that there has been an update. This problem is in Plesk 9.x and wasn't fixed in 9.2.1.

I came up with a temporary solution, which is not nice but somehow helps in real life - cron job updating SOA serial every hour:

/usr/local/psa/bin/dns.sh --update-soa domain.com > /dev/null 2>&1
