[Samba] Possible memory leak in drepl process on RODC

I'm running two samba RODCs next to two Windows Server 2019 based DCs in 
an Active Directory infrastructure.
The Domain functional level is 2012_R2 that is also set as ad fc 
functional level on the SAMBA RODC.
The samba version is 4.19.2-Debian from mjts repository running on 
Debian bookworm.

While everything basically seems to work fine the drepl subprocess is 
constantly growing in size until getting OOM killed by the kernel when 
already being around 4GiB in size.

Do you have any idea how to get to the root cause of this problem or how 
to fix it?

   Best regards
