Hello,

I have never seen such a behaviour with this plugin. I am not sure what would be the cause of this polling (probably the loop in xmpppy which is trying to retrieve new data from the server). In fact I only tried to add the support for MUC in this plugin, so I do not know exactly how everything works. Do you experience this kind of behaviour with the upstream plugin ? https://weechat.org/scripts/source/jabber.py.html/

If yes they might be more able to help on this issue than me :)

I have see the upstream jabber.py (changelog last entry is 2013-09-30 for v1.6) start to sit on the CPU and stay there. It works fine for a while first. I connect to talk.google.com.
