Forums mIRC Help Disconnection

Hello,

Since yesterday I am having problems joining a channel on undernet network. it seems that the minute I try to join the channel, I get disconnected from undernet and it automatically trys to reconnect again. it doesnt give any error, just says 'disconnected'. I know I'm not banned from the channel, otherwise I would have seen the ban message in my status window. I am not sure what exactly is causing the problem and how I can fix it. I can join other channels on undernet just fine, just this one channel keep getting me disconnected.

I run Windows XP pro SP1
Mirc 6.16
ADSL connection

Any help would be appreciated!

EDIT: I asked my friend to be in the channel when I attempt to join so he could see the quit error message and he said its "Max sendQ exceeded". what does it mean and how can I prevent it?
