Hello!
Looks like the replication Master/Slave is broken since the latest update.
Both servers were updated up to 4.2-2 release version.
In /var/log/univention/notifier.log file on Master I see the following events:
07.09.17 11:17:21.693 TRANSFILE ( ERROR ) : 7 failed, close connection to listener
07.09.17 11:17:55.102 TRANSFILE ( ERROR ) : 7 failed, close connection to listener
07.09.17 11:18:32.939 TRANSFILE ( ERROR ) : 7 failed, close connection to listener
07.09.17 11:19:08.450 TRANSFILE ( ERROR ) : 7 failed, close connection to listener
Meanwhile, in /var/log/univention/listener.log file on Slave I have these events:
07.09.17 18:18:38.180 DEBUG_INIT
UNIVENTION_DEBUG_BEGIN : uldap.__open host=ldap.example.com port=7389 base=dc=example,dc=com
UNIVENTION_DEBUG_END : uldap.__open host=ldap.example.com port=7389 base=dc=example,dc=com
07.09.17 18:19:43.539 LISTENER ( ERROR ) : connection to notifier was closed
07.09.17 18:19:43.539 LISTENER ( ERROR ) : failed to recv result
07.09.17 18:19:43.539 LISTENER ( ERROR ) : listener: 1
File /var/lib/univention-directory-listener/notifier_id on Slave contains number 2723249
The same file ( /var/lib/univention-directory-listener/notifier_id ) on Master has number 2723419
Connection between servers is not prohibited and simple tests:
From Slave
nc -vz ldap.example.com 7389
Connection to ldap.example.com 7389 port [tcp/] succeeded!
nc -vz ldap.example.com 6669
Connection to ldap.example.com 6669 port [tcp/] succeeded!
From Master
nc -vz ldap-slave0.example.com 7389
Connection to ldap-slave0.example.com 7389 port [tcp/*] succeeded!
show that replication can be performed.
Unfortunately, we observe the errors above on Master and Slave servers.
Could you give me the direction which I should dig in for resolving the issue?
Thanks in advance.
