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
