Unfortunately, since I cannot update the target, which is an embedded system, I have been able to help myself by disabling compression. Instead of calling rsync with the parameters -avz I use temporarily only -av for the affected target systems and the synchronization runs without problems.

The problem occurs since ubuntu 22.04 LTS with two different destination systems not running ubuntu but plain debian. The error did not occur under 20.04 LTS. Synchronisation runs fine for most other files, but always stops at the same (relative large) file. The file itself has also been changed on a test basis to make sure the file is not the problem itself.
