problem with recursive configuration and CNAMEs

[Leonardo Rodrigues Magalhães]

    Hi,

    i got maradns running as a simple recursive server, but i'm having 
some problems resolving CNAME records.

    maradns has no authoritative zone, it's only resolving the network 
requests recursively.

    i have tried enabled error logging (verbose_level=2) and also 
raising timeout (timeout_seconds=6) but i keep having problems resolving 
CNAME records.

    as i couldnt get any useful logs from maradns, the only thing i can 
see are my squid logs, which points nameserver resolutions failures:

    i have absolutely NO problems resolving names which are A records. 
The problem seems to be only with CNAME records.

    sometimes those CNAME records are correctly resolved, but other 
times they fail to resolve. A records, as stated, ALWAYS resolves fine.

    i'm running latest maradns stable: 1.3.07.09
