The following settings in the wasp.cfg determine how a user session behaves.
alarm information refresh:
alarm_dbcp2_max_active = 30
OC Page refresh general:
oc.jwt.refreshInterval = 120
Session expire timeout:
oc.jwt.expiryInSecs = 600
In the case of this issue. The user would be logged out when the 'oc.jwt.refreshInterval = 120' hit rather than when 'oc.jwt.expiryInSecs = 600' and cause the below error:
Release : 20.3
Component : UIM - OPERATOR CONSOLE
Resolved after the application of the following to 20.3.2. These should be included with 20.3.3 and should only be applied to a 20.3.2 configuration.
