These happen every few seconds and I have noticed an increase in frequency as more users are logged onto the Openfire server. We do not restrict the client types that can connect and I strongly suspect one of these client types is trying to do something non-standard. I’m sure the 20-30 people in our pilot IM implementation are not attempting to transfer files every second…
We are running Openfire 3.6.0a and are running a branded version of the Spark 2.5.8 client (again, not all users are connecting using it though).
Does anyone have any insight?
