I know that Igniterealtime is working on reliability of their software, so I'm hoping this question is on their list of todo's. But in the mean time, I've been a long time user of Openfire and Spark as an IM setup for a small business. One of the things I can't seem to work around is that when Openfire's server is unavailable for a long enough period of time, Spark will refuse to reconnect. This doesn't happen every day, but it does every week. I have remote systems that their internet is not very reliable at times. And their connectivity to our Openfire server can go away for minutes to even hours at times. And, Spark will usually reconnect if the connection is gone only for seconds, quite nicely. But after long enough time, Spark just goes into a permanent sleep mode, and won't reconnect even if requested by the user. Spark has be forcefully be stopped and restarted before the connection is allowed back. This might be an issue on the Openfire side too, not sure. Plus, I'd prefer Spark have a setting to not notify the user on disconnects, but just quietly remain minimized and try reconnection periodically without fail. Normally, these remote systems do stay up 24x7 if that is a factor.
Any ideas? I can't control the internet guys, so no need to go down the road of connectivity levels. Just that I'd like to see this re-connect problem improved.
