Well, something fixed it and I'd rather not break again it while fiddling around to try to find out what it was!
The nfs config is straight out of the box, nothing special and everything else runs ok. Maybe it was something corrupt in the data files and clearing them after moving the directory cleared the problem.

I am running my rrd files on an NFS share, having no problems. Have also ran several hobbit servers with the application binaries housed on NFS mounts; the app binaries & rrd files on NFS mounts; and just the rrd files on NFS mounts. Have been running Hobbit server with both the app binaries and rrd files on an NFS mount, for more than a year now. Unless there are some NFS performance issues on your network, housing those files on an NFS mount isn't the problem.

Got it working! I moved the data directory to the local disk and deleted the contents. After a while it all started working.
rrd obviously doesn't like nfs shares.

Well, moving the log directory to the local disk stopped the error messages but I'm still getting empty graphs.
Dean, the requirements show PCRE, RRDtool, libpng, OpenSSL and OpenLDAP libraries. I've got all of those:
(from ./configure)
Checking for RRDtool ... test-rrd.c: In function 'main': test-rrd.c:30: error: too few arguments to function 'rrd_graph' make: *** [test-compile] Error 1 Not RRDtool 1.0.x, checking for 1.2.x Found RRDtool include files in /usr/include Found RRDtool libraries in /usr/lib Linking RRD with PNG library: -L/usr/lib -lpng
Checking for PCRE ... Found PCRE include files in /usr/include Found PCRE libraries in /usr/lib
Checking for OpenSSL ... Found OpenSSL include files in /usr/include Found OpenSSL libraries in /usr/lib
Any more ideas?

Hi What I should have added is that I am seeing graphs but with no graph lines and no numeric data in them. The filesystem graph for example, shows all my mount points but then where the numbers are supposed to be it is showing nan.
I'm trying moving the data/rrd directory to a local disk now, I'll let you know how it gets on.

Rrdtool by itself is not sufficient for all the libraries hobbit needs. Please check the list of installed libraries against the hobbit pre-requisites & install any missing libraries. Then, when you re-compile hobbit afterward, run "make clean" before running "make" and "make install". The "make clean" command is important.

I built hobbit from source and initially it complained that the libraries weren't there so I installed the rrdtool package and tried again. This time it built so I assume that it had all it needed.
If you can let me know which files need what permissions I'll check when I check the nfs share suggestion later.

I've seen this rrd error in the past when rrd libraries, binaries, or data files had incorrect permissions or were missing (unavailable).

Hi The directory is a nfs share. I'll try moving the data directory to a local disk and see if that fixes it.

It's an error from the rrdtool library. I honestly have no idea what could be causing this.
Is the /var/sites/hobbit/non-secure//data/rrd an NFS filesystem? Perhaps there's some issue with locking on networked filsystems.
