If all you're doing is a /who on the entire channel, you won't get disconnected. If you're getting disconnected, then you have a script that's doing more than just a /who on the channel. Maybe it's doing a /who on each nick individually (as pointed out earlier in this thread), or you're sending some other information over the network for each nick. In either case, it's a script problem. If you show your script that does the /who and handles the RAW output of it, we could find where your problem is.
