Multiplayer disconnects after an hour of play (repeatable, random time to fault)

NeoHelios · September 24, 2018

Hi Community,

I have been experiencing problems with dropping from multiplayer servers. Can someone please advise?

I can repeat this issue, but not predictably; issue typically occurs every single online session after about an hour of play; sometimes sooner.

The steps to repeat are that I will be flying on any multiplayer server in the AV-8B, and about an hour into the game (sometimes sooner, sometimes later), the screen will freeze for about 1-3 seconds, and I will disconnect back into the multiplayer server selection menu with no servers listed. I must exit this menu to the main menu, and click back into the multiplayer server selection menu to see a populated list of servers again. Then I join the server again and spawn into my plane, and oddly I will get kicked again within in a minute or two. Have to exit DCS and restart app to get in and stay in, and this transition takes about 1-2 minutes.

Solutions attempted...

repair DCS - no change

power cycle router and cable modem - no change

update graphics drivers - no change

disable all mods - no change

play on a different server - no change

autoexec.cfg (network latency / packet size) fix - no change

gameplay without HMD - no change

upgrade GPU from GeForce 970 to 1070ti - no change

increase HDD page file size to 64Gb - no change

tech support from ISP - no change (slightly better latency, though)

reinstall OS - no change

connect directly to cable modem - no change

A few notes...

Single player works fine.

Seems to happen more often as I fly closer to ground objects.

After the 2.5 patch, DCS multiplayer was running fine. I don't remember specifically when this problem started since it's been going on for so long (4-6 months... Maybe longer).

Sometimes longer; sometimes shorter. Every single session that lasts over 45 minutes, minimum, though. So, like, minimum 45 minutes, but average one hour. Never lasts more than 90 minutes.

Issue seemed to be fixed after one recent patch, maybe about a month or so ago, but after the next following patch it went back to dropping.

I am playing on a server with anywhere from 3-20 other players. No one else currently has the same problem.

Happens on other servers without mods such as Inferno and Acrobatics servers, too.

Usually connected via ethernet to router, but getting same problem when connected directly to cable modem.

My cable modem performance is well within typical specs for StN and Up/Down power.

Had tech come out from ISP, and he said that the network is fine. They replaced one of my cables with better shielded one, and replaced unneeded splitter with a barrel connector. Technically, the signal improved based on PING statistics, but still getting same issue.

I also seem to get periodic decreased network performance on voice apps such as Discord and TeamSpeak, and other users report that my voice sounds choppy, sometimes.

Used to have Avast and MBAM, but since new OS install, I'm only using Windows Defender. Either way, the problem has been present under both apps.

Hardware Specs...

Win10 - newly installed, current drivers

16Gb RAM

Samsung Odyssey HMD

1070ti

i5-4690K

Cable Modem - ARRIS SB6141 8x4 DOCSIS 3.0 (purchased 2015)

.

ANY suggestions I have not yet considered are extremely helpful.

Thank you!

I was going to ask if you has any mods, beacsue the inegrity check now just dumps you to the main menu without warning after a random (apaprently) amount of time in a server - previuosly it wasn't even possible to join a server in the first place if the check failed.

But I see you have mods disabled, so it's unlikely to be the IC kicking you out.

Hi philstyle, thanks for the comment!

I am using a couple of sound mods, a label mod, and a pretty big texture mod that is required for our flights, but its standardized (i.e. in a repository for OvGME) and everyone else on the server is using it with no problems. I tested with NO mods on a different online server, and got the same problem; one of those "Inferno" ones; lasted a little over half an hour before dropping.

Thanks again

Are there server logs that could help the troubleshooting process?
