Specifying a syncrepl provider with an unreachable port results in high CPU
usage with slapd with slapd never terminating. Example configuration:

syncrepl rid=1
        provider=ldap://10.1.1.10:9292
        type=refreshAndPersist
        interval=00:00:01:00
        retry="60 +"
        searchbase="dc=howard,dc=chew"
        scope=sub
        schemachecking=on
        bindmethod=simple
        binddn="cn=admin,dc=howard,dc=chew"
        credentials=iwritecode
