I upgraded the Jabber server running jabber.earth.li from wpjabber to ejabberd earlier today. wpjabber appears to have been unmaintained for some time now and suffers from memory leaks that were causing stability issues (trying to consume 4.5G+ of memory isn't considered good behaviour).

Hopefully ejabberd will prove more stable; it's certainly being actively developed and supports more of the recent Jabber standards than wpjabber. Please do let me know if you see any issues.
