Here's the backtrace:

I'm using CentOS 4.x i386.

Please let me know if you need additional info.

This is the output when I ran rrdcached in the foreground:

rrdcached -p /var/run/rrdcached/rrdcached.pid -l
//var/run/rrdcached/rrdcached.sock -g
*** glibc detected *** double free or corruption (!prev): 0x094a4d80 ***
Aborted (core dumped)

Thanks a lot,
