Hi,

I have a master LDAP server and two slaves. The slaves use syncrepl in refreshAndPersist mode.

it's working until I see the message "connection_read(128): no connection!" in a slave log file. Here, I must restart the slave slapd to force the slave to be syncronized.

I post the syncrepl slave conf:

syncrepl rid=1 provider=ldap://ldap-master.blah.net type=refreshAndPersist interval=00:00:05:00 retry="30 +" searchbase="dc=blah,dc=net" schemachecking=on bindmethod=simple binddn="cn=root,dc=blah,dc=net" credentials=blahblah

It sounds like you have a device between the master and the replicas that cuts the connection after some period of time. If the operating system supports it, you can set a tcp keepalive in the sycnrepl configuration block in 2.4.22.
