Openfire 4.5.1 and problem with spark 2.8.3 if disable stream manager

I am currently using Openfire 4.5.1
And if I turn off the stream manager (false), then some users stop receiving some messages in Spark 2.8.3.
They are in the Openfire database, and they are in Spark 2.8.3 errors, but they are not in the client itself.
I checked the Openfire log - there are no errors or events at this time.
I’m applying a full log from 2 two clients, I turned off the stream manager on May 30, 2020, and as you can see from the logs, some messages stopped reaching.
