empty reqmod attribute

Hi,

I am experiencing a segfault on an OpenLDAP 2.4.44 instance. The architecture is: - 2 OpenLDAP - multimaster mirrormode - delta-syncrepl

The error seems to be in the syncrepl process, in a particular accesslog entry. When I give a look to the entry, I realize that some attributes in reqmod are empty, which seems strange because the value can't be empty in the directory. For example: reqMod: inetUserStatus:=

Does anyone know if this behaviour is normal, and what is happening?

Thanks in advance.

David
