[hobbit] Problems with writing client data while running several clients

[brandste at hebis.de]

Hi Rolf,

have you looked into your hobbit-log files?
New with hobbit i had the same problem and found out
that this happens when to identical (in my case conn-tests)
run on the server and collect the information for the
same machine:

page core-router
1.2.3.4  router1 #
[..]
page locationA
1.2.3.4  router1 #
[..]
Maybe you find identical lines testing the same in your bb-hosts.

Are the service you are monitoring for the virtual hosts equaly named?

Best
  Mathias
