I wonder what is the longest running XMPP service without a restart.
I watch a few servers running Tigase but then I restart them from time to time for software update with new features or bug fixes.
One of them is im.flosoft.biz which runs on quite old Celeron 1.33GHz machine with 200MB memory. Serves approximately 800 online users and works well for 75 days already without a restart. This is a development version of the Tigase 5.1.0 branch but indeed, Florian pushes me to release it as another stable version.
I have found however an absolute winner in this 'competition'. The last time I checked it earlier today the Tigase uptime time was: 657 days, 6 hours, 53 mins, 21 secs. This is a service running on MS Windows machine for online gaming website and most of the user connections are web clients connecting via Bosh. It is still running and working well!
I have also received a few other reports from people successfully running Tigase, as they say for 2 years without restart. If you have any specific data, number of days, the software version, please add a comment to this article. I would like to hear about your experience with long-running Tigase server.
