Just to provide more details. It seems that the multicast service is not functioning post update.
Here is a sample of the log file:
[10-23-25 10:34:19 am] * Starting MulticastManager Service [10-23-25 10:34:19 am] * Checking for new items every 10 seconds [10-23-25 10:34:19 am] * Starting service loopThe service is starting but seems to be stuck starting the service loop and never proceeds. I restarted the service, but the issue persists.
