Several game crashes during multipleyer with SorianAI [SOLVED]

[hwcrawler]

Hello to all guys, I'm facing game crashes during my multiplayer games.
I'm used to play FAF with some friends during the week-end, usually on Seton Clutch EP v.2 map (20x20 12 players). Our games are usually set up with two or three humans vs 6 Sorian AI (sometimes also some Sorian AIx).
I had no problems before September 2016 when some games start crashing after 20/30 minutes of gameplay. Now, since a couple of weeks, the game crashes allmost every time we reach 20 to 30 minutes of gameplay (9 times on 10) in lan or even through internet connection.
I've collected the game logs and the unhandled exception output (attached as 7z file).
Can you help me figure out which is the problem?

Thanks a lot for your help!

Is your forever log complete, or did you prune it?

You have a Boatload of "bottleneck" messages in there indicating that your network performance is really bad, but I cannot see, in the logfile, at which time the game started.

Th game disconnects locally and then crashes when it wants to remove the UPNP mappings. So, the crash isn´t the real problem, because it only should happen AFTER the game is finished anyway.

I am guessing that your internet connection is the problem. It seems that your router is removing the port mappings for FAF, thinking it´s an connection not used anymore. Maybe your Router doesn´t support UPNP - maybe it´s badly configured. I don´t know.

What you should try to do is to go through the trouble of setting up a fixed port forwarding for the FAF ports needed.

The FAF Wiki should be able to help you with that:

Edit: Rereading your post, you said "also in LAN". Did any of you guys install maybe a personal firewall software or upgrade their Operating systems software? Windows has it´s own firewall rules and maybe something is off there?

Also, LAN - if you are using FAF, your connection should still go over the internet, as far as I know. This just means, if you meet your friends at the same location, the internet of the location is the problem.

You should test if you disconnect from a public game without any of your friends and your friends should do the same ( from their home location, not at the LAN place ). If all but you stay in game, the problem is on your machine/connection. This way you can at least start searching for the problem.

Edit: If I am online in FAF, you can send me a chat message and I will stay with you in game for 30 minutes, to see if you disconnect from me. I have a very stable connection usually.

Thank you Vanguard for the log translation

Is your forever log complete, or did you prune it?

The log is complete, the archive was created with all my logs folder content plus the exception text.

My ISP uses wireless connections to cover my area and is doing some hardware upgrades on his antennas. Due to these upgrades, my network performances suffers heavy performance drops in some timeslots.
However adding the port forward and disabling UPNP solved part of my problems! My game always hanged/crashed at the exit probably because of the UPNP issue. My router is a TP-Link and probably the UPNP implementation is somehow buggy

Edit: Rereading your post, you said "also in LAN". Did any of you guys install maybe a personal firewall software or upgrade their Operating systems software? Windows has it´s own firewall rules and maybe something is off there?

We already add rules to windows firewall in order to permit FAF executable's traffic in all the possible ways on all machines. With FAF executables I meant "C:\ProgramData\FAForever\bin\ForgedAlliance.exe", "C:\Program Files (x86)\Forged Alliance Forever\FAForever.exe" and "C:\Program Files (x86)\Steam\steamapps\common\Supreme Commander Forged Alliance\bin\SupremeCommander.exe".

Also, LAN - if you are using FAF, your connection should still go over the internet, as far as I know. This just means, if you meet your friends at the same location, the internet of the location is the problem.

You should test if you disconnect from a public game without any of your friends and your friends should do the same ( from their home location, not at the LAN place ). If all but you stay in game, the problem is on your machine/connection. This way you can at least start searching for the problem.

As I wrote, also the LAN game (all machines phisically on the same room) presented the crash after 20/30 minutes. When we play in LAN we use only the FAF copy of the game ("C:\ProgramData\FAForever\bin\ForgedAlliance.exe") without the FAF client running. This way the client is able to find lan games, however we also tryed to directly connect all clients through the server LAN IP. Unfortunately, playing this way, no logs were written into the logs folder.

Anyway I've done a fresh install of the whole game (steam game, FAF client and the FAF copy of the game) using all the default folders on C drive. I found some posts on the forum about issues caused by game and client installed in non standard paths but my files were all on D drive.

Edit: If I am online in FAF, you can send me a chat message and I will stay with you in game for 30 minutes, to see if you disconnect from me. I have a very stable connection usually.

Thank you for your proposal, but on weekdays I have very little time to dedicate to FAF testing and this weekend, me and my friends will probably meet all toghether and try some more LAN games (from the same room). I hope the fresh install helps!
I'll return with our results next week.

My ISP uses wireless connections to cover my area and is doing some hardware upgrades on his antennas.

Oh wow, so we are talking LTE or simliar here?

That´s a boatload of infrastructure involved I am not familiar with here. It might be that your carrier, because you´re on a mobile connection, is somehow shutting down your ports. Then nothing you can do on your side will ever get the desired results.

needs more testing like getting your PC to another location with another uplink, to check, if it disconnects there too.

Well, let us know what your gathering showed. Best of luck.

Hello Vanguard, the wireless connection is based on a variant of WiMAX, my ISP refers to that tecnology as Wave. The latency is not so bad like LTE or other mobile connections (ping on speedtest is about 10/20 ms), however since they are upgrading the antennas I notice heavy bandwidth drops in certain timeslots (tipically the afternoon and evening). I hope the antennas upgrade will be completed as soon as possible
I'm sure not to be NATed because just after the line activation I asked my ISP to remove my subscription from CGN pool because I'm using a dynamic DNS service for some applications hosted on a little server in my home network.

I'm absolutely agree with you about the need for more testing but after removing UPnP and reinstalling the game from scratch on C: drive, I've never saw any game crashes. Unfortunately I cannot figure out which were the main problem (UPnP or installation path) because I've done both changes at once.
I'll be back with fresh news as soon as I understand which was the main solution for my issue!
In the meanwhile I will mark this thread as solved (by your first response about removing UPnP).
Thanks again for your helpfullness and kindness!
