Just in case you haven’t noticed: We’re experiencing quite a nasty bug (maybe, not proven yet) inside ejabberd which leads to a) ejabberd eating all of the available memory and b) afterwards having one thread run at 100% CPU. At this time, ejabberd stops forwarding packets and accepting new connections.
Just to keep you informed.
P.S.: We do have a Twitter account that might (!) have more up-to-date information than you can find in this blog: @jabberccc.de
