I've been setting up Xymon since I heard about it a couple of days ago. So far, its fantastic. Unfortunately, after a UPS malfunction that caused a whole room to restart, I have an inexplicable alarm. Take a look at this red alarm:
Memory Used Total Percentage Physical 4294964640M 4084M 4294967231% Swap 0M 4096M 0%
This is from a FreeBSD 7.x box that has 8GB of physical RAM and 4GB of swap. According to "top", the physical memory is still about 6.75GB free.
I've restarted the daemon on the host in question as well as on Xymon's GUI/web server. I've even tried a bin/bb 127.0.0.1 "drop HOSTNAME memory" just to see if it would help.
I'm not even sure where to start on this. It was working well for a day or so before going bad like this. My best guess right now is some kind of "wrap-around" problem with an integer or something like that causing bad data in memory.
Suggestions?
Thanks in advance, Jaime
