Was the RRDfile already created when you received this error message? That 'might' lead to this issue. If it's not repeatable, I'm kind of okay for the moment.

It appears in log every poller cycle. I have a lot of users who can create new graphs and I can't say when the problem started.

[TheWitness]

Can you please update to the 1.2.x branch and let us know if this problem persists. I recall us fixing some issues around this in the last few releases.

[TheWitness]

Never mind, I think I've found it. Maybe an aggregate graph built from a bogus graph. We might want to log something anyway. For now, I'm going to mask the error.

@Izmenoff Test using the lib/graph_variables.php from the 1.2.x branch and report back.

Thanks! The fix works fine
