Hello, I have HA set up of keycloak 1.2.0.Final - two instances in cluster behind load-balancer. Sometimes (not every time) I cannot log in and have this exception in log file on one of the boxes. Is this a known issue or did I something wrong? Thank you, Roman Usatenko. ===================================================================================== 2015-07-02 23:42:24,811 ERROR [io.undertow.request] (default task-15) UT005023:
