My xymon server monitors over 1500 clients with no issues. When I see false alerts, it has always been a configuration on my part where I have 2 servers in my bb-host file using the same name on different IPs.

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.

I have 7 clients running. Each client has a different name. They are all sending data to the primary Xymon server. The alerts are reading 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.

Is there only one client sending data as this name? I 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'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?
