[hobbit] False Process Down Alerts

Seems to me your clients data is being truncated. Try modifying this in
your hobbitserver.cfg. You may want to set them appropriate size for
your xymon server. I have xymon running on pretty beefy servers so I
set these incredibly high, and even though they may exceed what xymon
actually allows (but it is not hurting me). Restart hobbit server after
making change to hobbitserver.cfg
MAXMSG_STATUS=30000000
MAXMSG_CLIENT=30000000
MAXMSG_DATA=30000000

I've managed to stop the flood of false alerts. I removed all of my
non-prod clients from the bb-hosts and shut off their client processes.
The problem seems to be somehow related to the amount of data the Xymon
server is trying to process.

missing processes, full file systems, and msgs errors. Here is another
sample of an unusual error. You can see the process list has a funky
break in it.

don't think you answered Lars' email.
What does the alert read and what does the data say?
Missing process? Too high of a load?

I verified with tcpdump that the data coming from the client is 100%
correct. It seems something on the Xymon server side is not handling the
client data correctly. Anyone have any other ideas?

Process Down Alerts
I'm run into a strange
problem with my Xymon server. I noticed today that I'm receiving random
false alerts for processes being down. When I look at the process list
output in the alert it looks as if the data coming from the clients
isn't correct. Here is an example. Has anyone seen anything like this?
