fetch: Non-recoverable resolver failure

[Miroslav Lachman]

Hi,

we are using fetch command from cron to run PHP scripts periodically and 
sometimes cron sends error e-mails like this:

fetch: https://hiden.example.com/cron/fiveminutes: Non-recoverable 
resolver failure

The exact lines from crontab are:

*/5  * * * * fetch -qo /dev/null 
"https://hiden.example.com/cron/fiveminutes"

*/5  * * * * fetch -qo /dev/null 
"http://another.example.com/wd.php?hash=cslhakjs87LJ3rysalj79"

Network is working without problems, resolvers are working fine too. I 
also tried to use local instance of named at 127.0.0.1 but it did not 
fix the issue so it seems there is some problem with fetch in phase of 
resolving address.

Note: target domains are hosted on the server it-self and named too.

The system is FreeBSD 7.3-RELEASE-p2 i386 GENERIC

Can somebody help me to diagnose this random fetch+resolver issue?
