Okay, this is embarrassing, but I'll post anyway in case someone runs into this.
I had originally installed Big Brother and BB clients. Then I migrated to Xymon. On the two systems in question, I had neglected to turn off and remove the BB clients. So.. I had 2 applications - only one of which had permissions to /var/log/messages and was getting flapping status.
bbc up at the top of the chkconfig printout and xymon-client down at the bottom.
I found it after turning the xymon-client off on one of the server and observing new messages saying that /var/log/messages was unreadable. Light bulb!!

I've checked all of my systems and no misconfigurations like that. I also disabled the msgs report on the server and cleared all of the msgs status for the two servers and they are still reporting the issue of not being able to read log files.
I guess the next thing is to clear the entire host off the server and wait to see what happens.

Group ownership for /var/log/messages is set to root:xymon with proper permissions, so it should be able to read it. When I su to the xymon user, it can get to that file just fine.
Look at the IP address reporting the issue, possibly you have two systems reporting under the same name.

There is nothing in analysis.cfg that is watching either /var/log/messages or /var/log/fail2ban.
I cleared msgs from the server. Restarted the client. The issue keeps coming back.
Any ideas?

I had that error once when I had a space after the file name in analysis.cfg
If you can't find that file name maybe there's a shell eval that includes it somewhere?

Nothing I can find is testing for this file and the permissions are such that xymon can read it.
Any clues on where to look to find what is causing this?
Thanks.
