Just some thoughts and things you can check:

* Do you move only one or a few user objects or a large number at once?

* Does it happen also for other objects (computer accounts or groups)?

* Have you checked if there is maybe no free RAM left?

* Does it work after you restart Samba or reboot the host?

* I guess you already checked that the mount point, where your Samba
databases are located, is not full.

* Does "samba-tool dbcheck --cross-ncs" reports any errors? Run it on
all Samba DCs.

* Do you see any errors in the log when you try to move an AD entry?
Increase the log level, in case you don't see anything interesting:

* Do you have multiple DCs? If yes, can you temporarily shut down Samba
on all DCs except one and connect ADUC to this one and retry. And then
do the same with an other DC. Just to make sure that it's not related to
one DC.

* Is this a new environment or is it an older AD that was more or less
frequently updated?
