    Force load balance sync?


    We are running several load balanced umbraco 7.10 sites and it happens that the umbraco.config doesn't get updated on the slave servers sometimes. I can't find any error relating to it in the logs. Is there any way of forcing a sync to make sure published content is the same on all servers?

    Additional questions:

    • Is there any special logging i can enable to audit load balancing.
    • Is it safe to copy umbraco.config from one server to another?

    We've had a similar issue at one point and it was down to the master server not being able to connect to the slave servers. You can determine which server is master by querying the umbracoServer table.

    On that server check the logs and you should see logging indicating what it thinks the URL of the site is check you can connect to this from server side. Also check that there are no logs with relation to keepalive.

    You may want to drop your logging level to Info which may reveal more as to what's going on (log4net.config and priority field).

    Yes you can copy the cache as an interim solution.

    Hope that provides some information
