Hi, All I confirmed the problem that was not deleted in syncrepl of V2.4.30. The provider operates it in "syncprov-sessionlog 100". After I delete 150 in a provider, and going syncrepl Only 100 cases are deleted in the consumer side. After examining it, the following parts seem to have a problem. servers/slapd/overlays/syncprov.c:2638 if ( sl->sl_num > 0 ) { int i; for ( i=0; i<sl->sl_numcsns; i++ ) { /* SID not present == new enough */ if ( minsid < sl->sl_sids[i] ) { do_play = 1; break; } /* SID present and new enough */ if ( minsid == sl->sl_sids[i] && ber_bvcmp( &mincsn, &sl->sl_mincsn[i] ) >= 0 ) { do_play = 1; break; } } /* SID not present == new enough */ if ( i == sl->sl_numcsns ) do_play = 1; } if ( do_play ) { do_present = 0; /* mutex is unlocked in playlog */ syncprov_playlog( op, rs, sl, srs, ctxcsn, numcsns, sids ); } else { ldap_pvt_thread_mutex_unlock( &sl->sl_mutex ); } Then, it corrected as follows. === - if ( minsid == sl->sl_sids[i] - && ber_bvcmp( &mincsn, &sl->sl_mincsn[i] ) >= 0 ) { + if ( minsid == sl->sl_sids[i] ) { + if ( ber_bvcmp( &mincsn, &sl->sl_mincsn[i] ) >= 0 ) { do_play = 1; + } break; } Is this correction wrong?
