Nodes issues: Unable to select configuration

[overnet]

I have converted the db to include nodes using the following:

For the central node

./zabbix_server -n 1 -c /etc/zabbix/zabbix_server.conf

For the child node

./zabbix_server -n 2 -c /etc/zabbix/zabbix_server.conf

Converting tables completed on both.

On central node I created a child node using Administration-->Nodes-->New Node

When I select this node (Or do anything in Nodes) this message appears "Unable to select configuration". How can I fix this?

Thank you,

Anyone encountered this issue?

Ok, after a deeper investigation I think I found the reason for "Unable to Select Configuration" error, it was because zabbix-server on Node 4 when I restarted it, could not bind to port 10051 according to the logs

 27082:20081201:194349 Listener failed with error: Cannot bind to port 10051 for server [ANY]. Error [Address already in use]. Another zabbix_agentd already running ?.
 26946:20081201:194351 ZABBIX Server stopped. ZABBIX 1.6.1.

So what I did was stopping the zabbix-agent, starting zabbix-server and then starting zabbix-agent.

Hope someone will find it useful.

Your last error message means that there is already something listening on that port (probably a zabbix daemon).
When you restart your zabbix daemon, it takes a while before the old instance is really dead, the default restart scripts do not see this, so you will now and then get a conflict with the old running instance.
