We have UM with 3 realms servers, realm1 and realm2(another instance) are on same server, and realm2 is on another server.
In Integration Server log below error are seen:
[ISS.0153.0998E] [WMM.UM.ALIAS.03] Alias IS_UM_CONNECTION was disconnected: state = STARTED; clusterTryAgainAttempt = -1
[ISS.0153.0049E] UM connection alias IS_UM_CONNECTION was disconnected from its primary UM session. The primary UM session will automatically attempt to reconnect 5 time(S) before stopping the UM connection alias.
and below is the error in nirvanalog for that particular period of time.
