I am experiencing the same problem. Dedicated server is crashing as soon as mission launches. This is happening since I updated the servers to 1.14.116216. There was no change in the mission I am hosting.

I found what causes the crash (at least on my mission). When players are spawned, they are a civilian unit and a respawn.sqf is ran to change them to independent. The respawn template looks like this:

class CfgRespawnTemplates
{
// Class used in respawnTemplates entry
class horde_respawn
{

		// Function or script executed upon death. Parameters passed into it are the same as are passed into onPlayerKilled.sqf file
		onPlayerKilled = "\skynet\scripts\killed.sqf";
		// Function or script executed upon respawn. Parameters passed into it are the same as are passed into onPlayerRespawn.sqf file
		onPlayerRespawn = "\skynet\scripts\respawn.sqf";
		// Default respawn delay (can be overwitten by description.ext entry of the same name)
		respawnDelay = 20;

};
class Spectator
{

		onPlayerRespawn = "BIS_fnc_respawnSpectator";

};
};

//

In the respawn.sqf, there is some code which causes the DS to crash:

_group = group _unit;
_newGroup = createGroup independent;
[_unit] joinSilent _newGroup;
_newGroup selectLeader _unit;
deleteGroup _group;

Commenting it out stops the crash.

Hope that helps you.

EDIT: Very similar to this issue: http://feedback.arma3.com/view.php?id=17989

Small update.

If I spawn the code with a sleep of say 10 seconds, then it stops the DS crashing. It seems to only crash if ran directly in the respawn.sqf.

So I would say that for me this issue is resolved - weird that it didn't used to do this in previous builds but now does for some reason.
