Remote objects synchronization problems

I use Qt Remote Objects to synchronize objects between a server and several clients.
The synchronization from source to replicas is periodic and it is controlled by a QTimer.
The application that uses all this has dozens of Qt Remote Objects to synchronize identified by their IP, port and name.
The application works, but if it keeps running for many hours or a day, several objects stop synchronizing.
Objects are very different in size and are synchronized every 250, 500 or 1000 milliseconds.

I use the simplest kind of synchronization, the one that uses a direct connection between a static source and a dynamic replica as shown in the following examples:

https://doc.qt.io/qt-5/remoteobjects-example-dynamic-replica.html

Are there any known problems in frequent prolonged synchronization of a large number of Qt Remote Objects?
