Ignore New Badge - Currently Processing an Existing Badge Tap

"Ignore New Badge - Currently Processing an Existing Badge Tap" Message When Tapping a Badge

PROBLEM BEHAVIOR

Occasionally when users tap in their badges they are receiving an error message saying "Ignore new badge - currently processing an existing badge tap." The user is never logged in, and the system must be rebooted to recover.

EXPECTED BEHAVIOR

When a user taps their badge, they should be logged in normally.

AFFECTS:

XA 4.11.4 running in Locking Kiosk Mode (LKM) on Windows 10.

ROOT CAUSE: Memory leak in UserNotification

A bug was discovered in the component being used for User Notification where it would not release event callback method references, so objects would never go out of scope. This would result in unbounded memory usage which eventually caused a number of problems including this one.

RESOLUTION

Upgrade the client system to 4.11.5 (or higher).
