Hello,

I am experiencing the same issue. Here are the logs I obtain in the syslog:
2024-01-24T09:38:16.810558+01:00 ldap kernel: [ 1553.168747] slapd[13335]:

2024-01-24T09:38:16.840012+01:00 ldap slapd[13342]: Stopping OpenLDAP:
slapd.

To reproduce, simply activate the dynlist module and try to make an LDAP
query. In slapd.conf add:
moduleload   dynlist
overlay dynlist

Thanks,
Saïd
