Problem: Linux dom3 servers keep dying.
 
I've set up a linux machine pretty much for the purpose of running Dom3 games.

Unfortunately, Dom3 will not stay running for any length of time. I'm at my wit's end on this one.

Here's an example of what shows up in the log when one of the servers die:
Code:
gameserver got packet 9
tcp_get2hfile: gname:dawnofdominions pl:3
tcp_get2hfile: pl 3 len 5007
tcp_get2hfile: saving as /home/kenlon/dominions3/savedgames/dawnofdominions/early_marverni.2h
/home/kenlon/dominions3/savedgames/dawnofdominions/early_marverni.2h
N<E5>got gick fel!
savefile: error opening file
N<E5>got gick fel!
savefile: error opening file
  Sound deinited
I also ran strace on one of the dom3 processes, and as far as I can tell, it's losing the ability to read from/write to /home/kenlon/dominions3/savedgames at random - which is weird as hell, because I set the damn directory to 777 so anyone and anything can write to it.

Help!

Re: Problem: Linux dom3 servers keep dying.
 
I havent seen that one.
Does this work?
file /home/kenlon/dominions3/savedgames/dawnofdominions/*

you might try using the --preexec switch to have a pre.sh save all environmental variables to a text file.
touch env.txt
env >env.txt
set >>env.txt

The above will tell you if its something about files in general or just the 2h

is there a directory quota?
is there a security protection against binary files?

Re: Problem: Linux dom3 servers keep dying.
 
another thought..
is this sporadic? maybe its a clash. Maybe its two player files coming in at once. Does the server have quality controls on the number of streams and instances that one user is allowed to grab?

Re: Problem: Linux dom3 servers keep dying.
 
File is able to read all the files in all the game directories.
No quotas of any sort in place. Not sure what you mean by "security protection against binary files".

Something I only just thought of - I've been using a script to kick off all four servers at the same time. Could that have something to do with this? I know that means they end up with the same temp directory, but in any sanely written program that shouldn't matter.

It shouldnt.
But in general I take great steps to avoid running games at the same time. Just for load sake

Re: Problem: Linux dom3 servers keep dying.
 
Its not supposed to need it but for my scripts (for other reasons) I create the game directory manually with a mkdir command. You might try that.

anotherkenlon June 20th, 2010 08:21 PM
Re: Problem: Linux dom3 servers keep dying.
 
The directories are there, though.

And now a couple of the servers are just looping when people try to get their turns:


tcp_putturn: gname:duskofdominions pl:70
tcp_putturn: no turn file (/home/kenlon/dominions3/savedgames/duskofdominions/late_pythium.trn)


It looks like the same damn thing - it can't read the directory. But I've set dominions3, savedgames, and the individual game directories to 777 and it *still* craps out.

Aagh!

Re: Problem: Linux dom3 servers keep dying.
 
Just a quick thought: Who is the game server running as?
If it's not you (kenlon), try that. Alternately, try changing the owner of the savedgames directory to that user.
Shouldn't be necessary, but it's the only thing I can think of.

It's running as me - I'm spawning the servers via a small script.
