[Xymon] New server causing issues with CONN test

[Poppy, Ben]

I'm having a pretty strange issue. We have our existing hobbit servers running on Fedora servers running hobbit 4.2.0. I'm working on installing brand new servers that will be running CentOS 6 64-bit and the latest version of xymon (4.3.3 before I saw 4.3.4 today). I did not see a fix to my issue in the 4.3.4 change log though, so figured I'd post here.

In doing my update, I install the brand new server from scratch. Basically install CentOS 6 as a web server install, and then add in all the bits xymon needs (pcre, openssl, openldap, rrdtool, etc).. Then I compile and install xymon to /usr/lib/xymon. Next I copy over the bb-hosts file to the hosts.cfg, and follow the "migration" steps to get the data and configuration files over. Then I turn on xymon on the new server.

Within a few minutes, 4 servers turn to red alerts on CONN on the existing Fedora based Hobbit servers. They begin flapping on and off of red alert until I shutdown the new CentOS xymon server. Within a few minutes of the new server being shut down, the alerts go away for good.

I have tried going to Centos 5 32-bit, 64-bit, even trying xymon 4.2.3, or all the way back to hobbit 4.2.0 all with the same result, and the exact same 4 servers each time.

I'm completely at a loss here. Does anyone know what may be causing these issues where the only difference is the OS being used (the distro, that is)?

I just want to get our monitoring server upgraded to a stable OS, with updates, and get xymon up to date as well.

Thanks,
-Ben
