This alarm indicates that the real-time updates on the Port monitor are lagging behind and stale port states will display until all messaging has been removed from MSMQ.
Medium
The real-time events displayed in real-time monitors will not be accurate.
You can Purge the IvrInboundData queue to remove all the messages from MSMQ. However if you do this, the purged data will not be able to be reported on for example Port and Hunt Group reports.
Over time and with decreased traffic, the messaging will eventually be removed from MSMQ and real-time functionality will return.
