Borge,

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

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

Thanks for the help,

Dawid

Borge, 
 
According to the company I host with, it was several thousand connections from my \
username which brought down the server that hosted about 900 odd domains. Needless to \
say, I wasn't very popular :( 
I'll ask the sysadmin to scan the authlogs (or other logs) or even better send them \
to me so that I can analyze it... 
Thanks for the help,

you get several thousand logins in a matter of minutes?
Due to the KIO several logins is inevitable, but I don't think \
its possible to ... lets say 3000 logins on 3 minutes, \
the server would for sure stumble, but so would your \
computer, you sure your data is correct? 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 is 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 hours, somethings really fishy. Or you got a couple of thousand users trying to access the \
server fairly often ;D
