Multiple Xymon Servers

[Ken Mink <ken (at) minktech.com>]

We've got two xymon servers running 4.3.0-0.20090209. The clients are 
mostly hobbit 4.2.0. The goal was for the servers to run in parallel and 
stay in sync. I don't know if I did something wrong, but we're having a 
problem with the trend graphs and rrd. The rrd-status.log is full of 
messages like:

2009-05-19 12:26:02 RRD error updating 
/var/opt/hobbit/rrd/myhost.mydomain/la.rrd from 10.15.50.111: illegal 
attempt to update using time 1242750061 when last update time is 
1242750061 (minimum one second step)

Each client has
BBDISP="0.0.0.0"
BBDISPLAYS="10.15.50.10 10.15.50.12"
in it's config so that it's sending data to both servers.

Both servers have the same in their hobbitserver.cfg file.

Doing this made sense to me so that if one server went down, it would 
still be getting client data. Also, we can disable/enable things on one 
server and the other show the appropriate status. Only one server is 
running bbpage, however.

Did I configure things incorrectly for multiple servers or is there a 
deeper problem?

Thanks,
Ken
