[rrd-users] 500 Server Error in Apache

Wed Aug 15 15:38:11 CEST 2007

I think I have found my problem and all is working now. I had
duplicated the variable names for the CDEFs. If you have one duplicate
variable name rrdcgi will tell you and not generate a graph. If you
have more than one duplicate variable name rrdcgi will just seg fault
and crash. Once I made sure all the variable names were unique all
rrdcgi activity went back to normal. Thanks for the help.
