I use rrdtool and rrdcached from a PPA:

root@lin:~# apt-cache policy rrdcached
rrdcached:
  Installed: 1.4.8-1.1~ppa14.04+1
  Candidate: 1.4.8-1.1~ppa14.04+1
  Version table:

        100 /var/lib/dpkg/status

root@lin:~# apt-cache policy rrdtoolrrdtool:

But I have segmentation fault only in Ruckus devices, in wifi module.

Seems as something wrong with your rrdtool..

Do you use rrdcached or
you are one of those who updated rrdtool to 1.4.8?
