(ITS#5832) Networking and Replication.

Full_Name: Nils Hammar Version: 2.4.13 OS: CentOS 5.2 URL: Submission from: (NULL) (194.17.253.72)

When running syncrepl between two nodes in MirrorMode the communication works as it should until there is a disturbance on the network stack on either node.

This is applicable to Linux where iptables is used to filter traffic.

Example: Node A and B are running and updates on A are replicated to B. An update is done on iptables on B and the iptables is reloaded through "/etc/init.d/iptables restart". Any further updates on A are no longer replicated to B until the slapd service is restarted on B.

So it seems to me that there is no 'keep alive' or similar functionality in the networking that catches this kind of situation.
