Hai
I guess that an object becomes undefined, and you are still doing
something on that object.
This happens often if there is a mysql timeout.
var sql = new Ape.MySQL("ip:port", "user", "password",
"database");
sql.onConnect = function() {
Ape.log('Connected to mysql server');
}
// fast forward two days, depending on your mysql setup
// the connection behind the sql object is closed by now
sql.query("SELECT * FROM table", function(res, errorNo) {
Ape.log( "WTF" );
});
I've been bitten by this mysql timeout that's why I remember (search
the newsgroup). But it could also happen on other things.
e.g.
Ape = null;
Ape.log( "WTF" );
Try to pin down the problem, by wrapping them up in try/catch blocks

Hi all,
I run a platform to play one-on-one games online. Most games are
played human vs AI (artificial intelligence) and for online games
(rated), the AI is hosted on the APE server to prevent cheating.
Of course, having AI on the server is not recommended because it is
CPU intensive. However, this should not really be a problem as when I
have more players, they will play against each other and there is
therefore no need for an AI at peak times.
Well, in reality, I have an issue and it is not easy to see where it
is.
The symptoms are:
The AI stops abruptly without giving any error. To be accurate, it is
not only the AI, one or two other functions related to the refereeing
of games also stop abruptly from time to time.
By stopping abruptly I mean the function stops without being
completed. And it does not tell anyone.
I noted that this only occurs when:
- lots of users are connected at the same time (so lots of AIs
working
at the same time).
- the server has run for a few days or weeks (the APE memory
increases
slightly over time, but it never goes over 110-120MB).
Please note the machine is more powerful than needed and that issues
are not related to any other activity on the machine. So the problem
lies within APE (APE itself or my code).
Have you got any clue why APE stops functions abruptly? Or how I
could
find the issue?
Thanks for your time!
Nicolas.
PS: my AI routines take only a tiny fraction of seconds (the AIs can
play 1,000 moves per second).
