To me it indicates that you don't have a good facilitator in discussions. IMO one of the nicest things I've ever learned is the "silent thinking" bit. Basically: don't say anything, people write post-its, then people present that. This avoids usual influential people from speaking up early and everyone just focussing on one or two ideas. I've often been surprised what some people come up with.

If above is not enough to get an agreement, let the two people work it out on their own with a limit on how much time they can spend on it (and really limit this time). No need to have an entire team listen in or extend an existing meeting for ages (meetings should be brief).

Aside from that, sometimes you just need to do. So something like "it's not a perfect decision, but what you're saying is known and now it is time to do".

I'm from the Netherlands btw, though 50% of my colleagues are foreign.

People not knowing what decisions have been made, and which have yet to be made, is poor communication. The first thing you do after making a decision is communicate it unambiguously.
