I have a redhat 9 (2.4.20-20.9) server that's a Big Brother server (1.9c).  
The server is a Dell 1550 with 1GB RAM and a 1Ghz CPU.  Last week, I
installed larrd-0.43c from www.deadcat.net.  Larrd requires RRDTool so I
grabbed the latest source I could find (1.0.45), compiled and installed.

It seemed to work fine until my server froze up pretty badly one day.  I 
could ping it but could not ssh to it.  On the serial console, I got a 
login prompt so I attempted to log in.  After taking my password, it too 
froze up.  I had to power cycle it.

I thought maybe this was a fluke, so I didn't disable larrd/rrdtool.  Over 
the weekend, it froze up again.  This time, no response at all on the 

I've searched my system logs but found no clues.  The only clues I had 
were the first time it hung, big brother was reporting that the cpu was in 
system/kernel space 99-100% of the time and 0% idle, 0% user, etc. 

Anyone run into anything simliar with larrd or any other tools that use
