Yes, this is a must need if there are any.
My server tends to crash after a few hours due to unknown reasons and it would be great if they had some way for it to automaticly start itself back up. Hope something like this gets released in the near future.

I\'m not sure this will reboot the server.. because it\'s purely for Ubuntu itself, but the logic is there.
Moving on.
Well making a timer or timed script isn\'t very hard or heavy, so we\'ll skip that.
I would have the script print out into chat a warning saying \"the server has just been saved, will reboot in 2 minutes, and that any progress during those two minutes may be lost.\", then run the /shutdown command with a parameter of 120.
The only thing I can\'t really give you is the actual command to launch the server back up.
I don\'t have the files with me right now (at work), but starmade doesn\'t have a dedicated_server_launcher.jar or something, right? With the way you start and host a server right now (and it\'s great) you\'d just have to run that program at after the shutdown and voilà.
I haven\'t looked into or know right now how to give the 2 first commands as an in-game admin, but I\'m sure that can be worked around. Worst case scenario would be no warning and then just close the server from the outside like you\'d kill any program. This could frustrate the server users, so I\'d advise a welcome message that specify either the hours of reboot or a warning that it happens hourly.
Hope this helps.

My Host has made a Restart Script whenever the server is COMPLETELY down/crashed. I don\'t know for sure if this is the right one, but I took it from the FTP. I\'ll ask him later if he uses this one currently. But this is a \'launcher.bat\' located within the StarMade folder and looks like this:
@echo off
title FH - StarMade Server Launcher
:launch
echo Launching server...
call java -Xms1024m -Xmx2048m -Xincgc -Xshare
ff -jar StarMade.jar -server
goto launch
@echo off
title FH - StarMade Server Launcher
:launch
echo Launching server...
call java -Xms1024m -Xmx2048m -Xincgc -Xshare
ff -jar StarMade.jar -servergoto launch

So originally I wanted to do something nice and simple, that makes use of some of the native functions of Linux for just such situations as this. A simple 4 line script.
until StarMade-dedicated-server-linux.sh; do
echo \"StarMade crashed with exit code $?. Respawning..\" >&2
sleep 1
done
However from what I can gather, when StarMade crashes, it doesn\'t *really* crash. At least not as the OS sees it. See, StarMade crashes gracefully (at least every time I\'ve seen) and actually saves its state and shuts down properly. This means that it sends a termination code of 0, and thus this script does not run. It looks at the shutdown and says \"Oh, no, you meant to do that. Guess I don\'t need to do anything.\" So while I am glad that StarMade even manages to crash reasonably gracefully, it does cause a problem here. That script does not work.
After some minor frustrations that are typical of toying with scripting languages you don\'t use much, I got the below script put together and working. It checks for instances of StarMade.jar in the processes list and starts the server if they\'re not located. This does have to be put into crontab, unless you have another way to make the thing keep checking. Mine is set to check every 5 minutes, I figure that\'s probably fine. Hopefully this helps people some.
EDIT: I found a better way to set the script up that doesn\'t require cron. In hindsight, I feel silly for not realizing this previously but oh well. I\'ve been running this script for a few days now and it seems to work well. You can change the sleep time to whatever you want it to be.
#!/bin/bash
while :
do
if [ \"$(pgrep -f StarMade.jar)\" ]
then
echo “$(date “+%m%d%y %T”) : StarMade is running already”
else
echo “$(date “+%m%d%y %T”) : StarMade not running, launching…”
cd “$(dirname “$0?)”
/opt/java/bin/java -Xms512m -Xmx4G -jar StarMade.jar -server
fi
sleep 2m
done
until StarMade-dedicated-server-linux.sh; do
echo \"StarMade crashed with exit code $?. Respawning..\" >&2
sleep 1
done
