My server is also affected by this issues, and I can't solve.
I also try erasing all system and doesn't help, it's keeping crash several times.

UPDATED 09-22-2018

After looking deeper in the problem, seems this problem appeared the first time in 2017, but it's still there.
Looking HERE you can see that it's probably related to the clients connects while the server is still loading stuff, keeping server crashing in the starting sequence.

To prevent this, you can try to use a firewall to block connection while the server is loading, give to it a couple of minute to finish the loading sequence, and then open again the DCS Port.

Don't worry about your server inside the multiplayer list, as soon as the firewall restore the connection policy to allow on DCS Port, your server appear in the multiplayer list.

Tested personally today for the whole scheduled server restart, works fine!

The Aerobatics Online servers weren't affected by this bug for a long time, but it's crashing us multiple times on every restart now since the last two updates. To put some numbers behind it:
2018-09-19: 6 crashes
2018-09-20: 8 crashes
2018-09-21: 4 crashes
2018-09-22: 12 crashes
2018-09-23: 5 crashes
2018-09-24: 4 crashes
2018-09-25: 8 crashes
My automation scripts detect the failure and restart the server, but it takes time and significantly delays server availability when multiple crashes occur in a row. Keep in mind there are only four scheduled restarts in a 24 hour period on AO.


I'm just curious what mitigation steps people have taken with regard to automation. I presume that this is related to players connecting early during DCS loading, but my logs don't show evidence of that. Assuming it is that, though, are you server operators manually setting a Windows firewall rule when DCS starts loading and then change it back when DCS is up? Or are you doing something else? I've been able to live with this bug for awhile now, but it's gotten way worse and need to do something.


Two crash logs are attached which represent the many others that collect.

We had the exact same crash 30 minutes into the mission twice today. Only a different mem address. Then it’s just not our server.

Same on our server...
No solutions found here ATM, sadly.
Edit : it is a private little server and that can appen when the first player was connecting, but hours after server startup. For me not related to mass joining or joining during startup nthing to do with mitigation sadly.
