[Xymon] DNS timeout not working

[Raul GN]

Hi,
    Since I installed version 4.3 (previous version may have same issue) DNS
timeout stopped working. In Task.cfg I put this line:

CMD xymonnet --report --ping --checkresponse --timeout=10 --dns-timeout=15

But dns-timeout didn't solve the issue.

When I put a host that doesn't response to DNS, time-out is too large:
Wed May 4 16:03:59 2011 dns NOT ok Service dns on HS-755 is not OK : Service
unavailable
 Timeout
Seconds: 178.169

If I remove dns-timeout parameter DNS check time is even greater:

Service dns on HS-755 is not OK : Service unavailable

Timeout

Seconds: 356.336


With DNS test enabled:

Does anyone know how to fix it? If I put many DNS test failures the whole
xymon get purple because xymonnet don't do DNS test in parallel but in
serial (one after other).

thank for you time,
