1 Rad requires venting every 6 weeks!

[poolebybirth]

Minor prob but as i'm online would like to ask your expert opinions if i may?:

one of my bedrooms (upsatirs) requires venting every 6 weeks or so.. it is the only one that requires this. Is this common? The system is open vented, the static head of the pump if good as is the positioning, the ballvalve is not constantly in use-indicating no leak, the system has inhibitor in it, always has done. The radiator looks ok??

Any thoughts to why this could be happening? Should I be worried?
