Spontaneous logged out from management console

[msche]

Description:
When clicking through the WSO2 management console I spontaneously get logged out sometimes. I have deployed 2 instances of Identity Server. Within the logs there are no indications something has been gone wrong.

Cluster seems to be using hazelcast correctly, in the log I see statements like:
