Any insight how to mitigate this issue on older servers? Reportedly, Openfire 3.9.2 resolves this issue, but it doesn’t appear to be downloadable to the public.
It’s also reportedly recommended to disable XMPP Compression. I found the xmpp.client.compression.policy setting (http://community.igniterealtime.org/docs/DOC-1061), but I don’t know if this is a solution or not. It’s not a property by default in our System Properties, and I figured I’d ask before tinkering.
