Update - Saturday, October 20, 2007

Bug fixes
Fixed an exploit that could be used to crash the game for every player in an instance.

Guild Wars Wiki notes
This update had a bug which caused many players to be disconnected with "Error 7", and it was quickly followed by a second emergency build to fix the problem.

Nice they fixed my exploit.

It consisted into sending a health ping packet with wrong textrefs, if you try that after this update you get an error 7.

EDIT: I am quoting what Gaile stated on her talk page so that nobody gets any bad ideas.

But those who learned of this exploit and attempted to use it after we rolled the build will most likely find the account banned. -- Gaile 00:25, 21 October 2007 (UTC)

The exploit was disabled with a correction, as I mentioned, that also puts in place a reporting system that will allow the team to see if anyone tries to use the exploit. (I should clarify: Even if the exploit is closed, trying to use it is still disallowed by the UA, and we take that provision very seriously.) -- Gaile 08:09, 21 October 2007 (UTC)

So don't try the exploit or you risk being banned!

When they gonna fix that you can't report a leech in FA after the battle starts? The leech box is blank and you can't put a checkmark into it?

Yeah, I like how you can only report a leech before the battle starts. That is brilliant.

It wasn't always that way it just started the last couple of days. Either that or these hackers have figured a way to keep themselves from being reported after the battle starts. Anet needs to look into this. The Leechers are returning to FA again.

Sigh.. a.net has to basically shut down for a few hours and everybody panics. If anybody who has played another online game will know, sever maintance and cooldowns happen VERY often in other games (like once a week WoW is shut down to be updated). A.net has some of the most stable servers I've ever seen, only being shut down like 4 times (and twice for rollbacks). That's a testament to their skill at coding since they don't have a lot of money to maintain servers.

Indeed, I think. I was gone for the latter parts of Oktoberfest, and I cameback only to find Err=7. I closed GWs, and poof, issue fixed.

It may have been fixed quickly (and on a saturday!), however I was in the middle of doing delicate surgery and lost the patient.

Text reference. I think it has something to do with codes.

Three cheers for pablo!!!

Well done mate, excellent spotting of this error. Personally, I don't understand how you made the error occur (I hate beeing noobish.

) but nice work. And also, hats off to Anet for fixing this bug within 24 hours.

When the server sends you text that translates when you change your GW's language, it actually sends a reference to that text in Gw.dat. As the server didn't check if the reference was valid for the Health/Energy/Morale Boost/Level ping packets and instead of simply sending an OP Code to the server telling it to make the ping packet itself, the client makes up the ping packets and the server only "relays" them. So if you sent a wrong textref to the server it would simply relay it to the other players and make them crash.
Hope more people understand now

Errr.. they pay for the gigs and gigs and gigs of bandwidth that the game needs!

If you know anything at all about servers and networks you would know that this stuff is expensive! Don't think about comparing it to your home internet links, as commercial grade connections are a whole different ball game and in a whole different league when it comes to costs.

Out of curiosity, what were you forcing their clients to try to reference? Arbitrary garbage I presume? If you knew the right handles, could you have forced their client to reference an instruction and interpret it as an action to be performed instead of a text string to be treated as data? Thus Rahja's panic state that you could completely take over someone's account?
