I'm not sure why you'd run that in cron, it seems a bit crazy!
I don't know if it's safe to use with rrdcached, it might be. rrdcached saves updates and pushes them to the disk-rrds, rather than storing copies of the changed rrd, so it's probably fine.

They only started to appear after enabling rrdcached, and then after a few days of rrdcached running we noticed they had started working on their own! However it might have also been after the spike cleaning cron-job had run; for i in /opt/observium/rrd/*/*.rrd; do /usr/bin/php /opt/observium/scripts/removespikes.php --rrdfile=$i; done; But generally speaking this does seem to be an rrdcahed oddity. Things are defintly better with the latest versions of RRD so compiling the latest is worthwhile J PS; Also is the spikes script safe when using rrdcached? Cheers, Andy.

It's an rrdtool bug causing a segmentation fault. Find a different rrdtool version and it'll probably go away. Unsurprisingly, rrdtool segmentation faults aren't anything we can do anything about. adam.

When we have rrdcached enabled with ‘$config['rrdcached'] = "unix:/var/run/rrdcached.sock";’, the rrdtool command also shows relative locations for the rrd’s. However the relative path cannot be the problem as it does work most of the time! Here you can see below, they are both the same (they both use relative paths vs the full path). I went onto the server and ran the command on the cli ( the one which results in “Error Drawing Graph”, and it works perfectly! The created .png file is fine ). Adam, I assume that it is Observium which is building this command string. And I have checked our config.php and I am very confident it is correct as the only variable which defines any path relating to rrd’s is the above rrdcached one. I cannot even see a variable in the default incudes config.php so not sure where you are getting this path from to help debug this? – But as mentioned the relative path doesn’t seem to matter.
