Original GitHub issue: https://github.com/GameServerManagers/LinuxGSM/issues/3763

As a dedicated game server manager, I run into issue managing multiple instance of ut99 ded server.
I am using systemd to launch them, and their is like a "mix" beetween process Ids.
It start ok, but stop/restart do not work individually , Its like they all stop together.

Systemd status result sample (1st instance, 3 in total):

systemctl status ut99server
* ut99server.service - ut99server Server
   Loaded: loaded (/etc/systemd/system/ut99server.service; enabled; vendor preset: enabled)

You can see the 3 instances are reported, which is not the desired behavior.
Others instances have:

systemctl status ut99server-3
* ut99server-3.service - ut99server Server 3
   Loaded: loaded (/etc/systemd/system/ut99server-3.service; enabled; vendor preset: enabled)

  Process: 19248 ExecStart=/home/ut99server/ut99server-3 start (code=exited, status=0/SUCCESS)

problem seems to be related to Tmux session being the same for all game instance...

Well, if you're saying that it's about tmux, did you keep that in mind?

Thank you for the link, I know that.

My installation is up and running since 2 years with no problem since... tmux, It tooked me time to figure out it was related, I was thinking something was wrong with ucc update..
Finally, tmux handling was the root cause because we are using the same tmux server for all game server instances, and systemd think they are all the same...
I can confirm it is not only limited to ut99, I have same behavior with ut2004.

I just analyzed the lgsm code and found a quick solution, which hopefully work fine with ut99 but might need more test with all other games..

In command_start.sh, command_stop.sh and check_status.sh, change
tmux <some options>
by:
tmux -L "${sessionname}" <some options>

This will create a new tmux with private pid for every game server instances, making systemd happy ... :)

Will test it on ut2k4 and co4.

Modifyed files:

command_start.sh.txt
command_stop.sh.txt
check_status.sh.txt

I can confirm it work just fine with ut99, ut2k4 and cod4 !
Now I can start/stop/restart each instance without killing others, like in old screen time ;)
