We started using Spark at 2.0.8 version and it was perfect but when this new version 2.5.0 became it started to be unstable, some of our users are being disconnected and reconnecting every 10 seconds. And with version 2.5.1 the problem persists. And with some users the program only disconnect when the user try to edit its profile or other configuration of spark.
Anyone else is with the same problems???
