Thats hard to say, there was never a statement why its not possible in Arma Reforger, but in DayZ or Arma 3.
Just speaking for me I would love to see more communities and servers in Reforger.
First, because the new new Enfusion Engine is pretty awesome and Arma always benefited from the variety of communities and mods.
Second, because it would help a lot to report bugs, server crashes and so on if more servers were active in general.

Thanks.
I checked it out with our mod and the problem seems to be fixed.

Update (Experimental Build)
I just checked if the issue still exists in the experimental build after the major update yesterday and unfortunately it does.
Below is a screenshot of the error message.
It turned out that the "borders shifted" so the mod version that could be compiled with the current release version could not be compiled with the experimental build without removing lots of content.

Thank you Geez.

Thank you for the info, i will have a look at that!

I forgot to mention that this problem occurs since the last major update 0.9.8.64.

Hey Geez,

Heloo Geez,

It seems like today's update 0.9.7.91 has fixed the issue.

Since the last updates the servers are way more stable, so it was possible to isolate the problem a bit and generate a diagram without other crashes.
Therefore figure 3 shows players and memory usage over a periode of 12 hours with high load.
