When multiple replica update vector (RUV) updates were skipped in fractional replication, RUV was not updated at the end of the session, and the next session restarted evaluating the same skipped updates. This update prevents the unnecessary replays.

Description

Workaround: Under extreme condition (if all updates are skipped and the list of them is large) replication can appear to be broken. A workaround is to apply periodic dummy updates on all servers. Those updates need to be replicated ones (not updating filtered attributes). Periodicity could be 1/h or less, depending on the update rate. Executed https://fedorahosted.org/389/attachment/ticket/48266/0001-Ticket-48266-test-case.2.patch //etc/sysconfig/dirsrv-* INFO:lib389:List from /root/.dirsrv INFO:lib389:list instance {'RUN_DIR': '/var/run/dirsrv', 'SERVER_ID': 'master_2', 'hostname': 'localhost.localdomain', 'ldap-port': 42389, 'ldap-secureport': None, 'DS_ROOT': '', 'deployed-dir': '/', 'INST_DIR': '/usr/lib64/dirsrv/slapd-master_2', 'SERVER_DIR': '/usr/lib64/dirsrv', 'server-id': 'master_2', 'SERVERBIN_DIR': '/usr/sbin', 'root-dn': 'cn=Directory Manager', 'user-id': 'dirsrv', 'CONFIG_DIR': '/etc/dirsrv/slapd-master_2', 'PRODUCT_NAME': 'slapd', 'suffix': 'dc=example,dc=com'} DEBUG:lib389:running: /usr/sbin/remove-ds.pl -i slapd-master_2 Instance slapd-master_2 removed. ========================================== 3 passed in 191.87 seconds ========================================== wrote pytestdebug information to /export/ds/dirsrvtests/tickets/pytestdebug.log Hence VERIFIED. Bug fix introduced a new regression, so marking this bug as ASSIGNED per https://bugzilla.redhat.com/show_bug.cgi?id=1243970#c10 and #c11. Tested with the latest build of 389-ds-base-1.3.4.0-18 build and found no crash for mmraccept tests. Hence, marking the bug as Verified. The test execution for mmraccept shows 2/67 FAIL which is the same as previous build 1.3.4.0-15.
