I knew about the TLS issue (we have our load balancers handle the decryption) but mod_pubsub wasn't. Something I'll have to keep and eye on for our cluster. Currently our ejabberd installation runs fine and has only crashed once in the last year and a half due to the disk it was on running out of space. Not that the processes had that kind of uptime though due to adding-vhosts-requires-restarts 'quirk'. -- Taylor Laramie
