I'm seeing the same problem on a pfc-1.3 install in a drupal site: http://thejapanesepage.com/chat (requires login, sorry)
I was looking through the source and changelog for http://www.jpfchat.com/ , and there appear to be changes that claim to prevent duplicate messages... I'm wondering if this relates to the same duplicate messages problem a few of us seem to be seeing?
From the history.txt file that comes with it...
- Code: Select all
11/28/09 v2.1.0
--------------------------------------
updated handling of xml requests to improve performance and eliminate possible duplicates.
altered pfclient.js to remove possibility of duplicate messages
We're also experiencing the same kinds of user disconnects even if the user just typed something... saying they timed out. Sometimes it happens after literally a few seconds... and sometimes it can be fine for hours, or even stay connected overnight while the user sleeps etc. But it's a real frustration when users are sitting actively chatting just fine and suddenly they're disconnected saying they timed out.

I need to update PHP in order to implement the latest memcache, so I'll be able to see if that has an effect on things. Other than that, all I can think of doing is removing it from Drupal... but I can see the same symptoms on my PHPBB linked PFC chat as well, although to a much lesser extent... so I don't think it's necessarily Drupal's fault, but perhaps the # of users, higher pings, using a database for session storage rather than the filesystem, etc.
Or at least be much less noticeable... it's so bad right now that for instance in "the game room" when using the quiz bot, you might see the score table repeat like 3 or 4 times... I even saw some messages repeating half a dozen times (6) etc. (and like the others said, refreshing the chat causes everything to go back to normal, and each message is only shown once as it should be)
