No; actually, the weird thing is that I'm having this
warnings ONLY for these two graphs:
o_admin-dev1_gauge_1024_X_freememK-yearly.png 
o_admin-prod1_gauge_1024_X_disk_rK_per_s,__1024_X_disk_wK_per_s-yearly.png

All the graphs are saved in the same disk, so space
shouldn't be a problem. There are no quotas either.
And all the other graphs for those machines and all
the graphs for the other systems are just fine.

I could try that, but I wouldn't want to loose the
information I have up to now. Is there any way to
avoid it? Would you recommend to delete all the rrd
files or just those two?

Sure, I can try to upgrade too. I'm using 1.0.41.

Thanks again,
