My local network uses Spark 2.6.3. The problem is losing connection in some random moments. The message “The connection ended with an error” appears and user can click the button for reconnection. I found this problem in 2 computers. In logs\errors it’s written that system cannot find some files in vcards directory. What I have to do?
would you consider upgrading to the latest spark?, other than that, server side info would also help. unfortunately the info that you supplied: Spark 2.6.3(very old) disconnect. the “system cannot find some files in vcard” seems unrelated.
Thank you for answer! Unfortunately, it’s difficult to upgrade Spark for later version. So it’s no use. So I can try to do something with server info. But which specific info is needed?
Trying to get server side logs from the same time that the disconnect happens might show something useful. You can maybe match the disconnect time on the client, and see what the server is saying the same time around.
I was checking log files, but no useful info was found. I still don’t understand the the reason of this disconnection.
Trying to guess without any data its almost impossible. maybe turn your logs to “trace”. see if that catches anything.
Besides that, there might be a real chance that the issue that you are encountering was already fixed in later versions off Spark. If there is some setting or anything, OK you should be able to workaround that. but if it is a bug in the code, then your only fix will be to update the software.
Did it used to work normally? then something changed? if yes, what changed? did you upgrade Openfire?(what version are you utilizing?).
