          Issue ID: 9584
           Summary: cn=config replication ops/refresh should pause server
           Product: OpenLDAP
           Version: unspecified
          Hardware: All
                OS: All

          Severity: normal
          Priority: ---

Looking into this crash: https://git.openldap.org/openldap/openldap/-/jobs/7286

The thread in question is running a plain syncrepl refresh while another thread
seems to have done the same. This thread fetched the entryUUID attribute of the
'cn=config' entry as 'a' and in the meantime, that entry has been rewritten,
with 'a' presumably cleaned up and returned to the pool, so addressing
a->a_nvals[0] is a NULL-dereference now.

This might or might not be related to the fix in ITS#8102.
