I believed that Rodinal and its clones were eternal. Now I developed a roll in Fomadon R 09 (expired in 2016 November) and I got almost blank frames. The film leader is not black, but grey. What is your opinion?

Sounds like it wasn't developed enough.

I also used some older Fomadon R09 and got nothing but blanks. I'm positive my dev times were correct so I'm pretty convinced it's not the same as Rodinal.

In my experience it lasts fairly long, if undiluted. Once diluted, a very short shelf life.

I have read more than a few reports of similar problems with R09.
If stored and used properly this is disconcerting and disappointing.
Rodinal users expect this developer to be reliable with long shelf-life.
My next bottle of Rodinal-clone developer will be another brand.

At the end of the day, it doesn't seem to be a problem just limited to R09.
I had the same issue of Adox Adonal and R09. Both undiluted and used as a one shot when required.
So YMMV, all I know is that I'm moving to Fuji SPD as a oneshot instead and no more R09/Rodinal/Adonal/Clones for me.

I mixed a fresh batch from undiluted stock and got blanks. So I really don't trust the stuff anymore. Pretty much only use HC-110 now (if I can get it) because that stuff seems to survive the heat in Thailand quite well.

A true Rodinal clone - made using the original AGFA formula, as most brands claim - should have extended shelf life in concentrate form.
IMO this is an essential characteristic of anything calling itself Rodinal, and a major reason many darkroom workers choose this developer.

A long, long time.
Diluted, one shot.

Those of us in cooler climates seem to be getting longer R09 shelf life, perhaps it is heat related.
Kodak HC-110 seems to last for decades in heavy syrup form if tightly capped, but I have heard that the non-US version is less concentrated?

This has more to do with the packaging than the developer. No chemical lasts very long, let alone 'almost indefinitely' in packaging that readily allows diffusion of oxygen.

It is most likely heat related. I live in Thailand and it's always hot with high humidity here. Most chemicals don't last long.

I'm in Brisbane, hot and humid. I keep my R09 in the fridge next to my other chemicals and they last well enough that I haven't had any issues.
My film goes on a higher shelf.

Ah maybe that’s what I should do also. I’ve had two bottles of the R09 go off in the last few years.

You could also try buying some glass bottles that seal properly to put it in, like:
