Hobbit monitoring help needed

[Peter Welter]

Hobbit (4.2.0-with patches) is running http-tests for a particular
system. This system is very unstable and Hobbit proves it, but now and
then the http-check for that host fails in a strange way.

The page output turns to YELLOW for 10 minutes(!) while each of the 5
tested URL's fail (status RED):

[snip]
Wed Jan 9 21:25:04 2008: Server timeout ; Server timeout ; Server
timeout ; Server timeout ; Server timeoutSeconds:

 http://some.url/ - Server timeout

Seconds:    10.06
[snip]

Now 1 minute later, this same test turns into RED instead of yellow.
Why first yellow, then red? And then all alarms are triggered at
once?!

Anyway, I do not understand Hobbit's response?!

Any help much appreciated,  Peter
