According to the company I host with, it was several thousand connections f= rom my username which brought down the server that hosted about 900 odd dom= ains. Needless to say, I wasn't very popular :(

I'll ask the sysadmin to scan the authlogs (or other logs) or even better s= end them to me so that I can analyze it...

Thanks for the help,

you get several thousand logins in a matter of minu=
tes?
Due to the KIO several logins is inevitable, but I =
don't think its possible 
to ... lets say 3000 logins on 3 minutes, the serve=
r would for sure stumble, 
but so would your computer, you sure your data is c=
orrect?
It's like 16 connections a sec...
more like one connection per file, and quite a few =
files I must add ;D
Whatever it is, its not Q' fault ( can it be?). Q i=
s using the KIO backend for 
connecting.

If you're not experiensing any showstoppers on the =
client side, I would read 
throught the authlogs to so whats going on with the=
 server... Of course if 
the authlogs really is growing 2megs in matter of h=
ours, somethings really 
fishy. Or you got a couple of thousand users trying=
 to access the server 
fairly often ;D
