Hello,

I have a load balanced environment and my Umbraco version is 7.2.6.

Occasionally when creating new content it can sometimes take up to 15 minutes.

Today there was a request timeout error while publishing new content and I found in the umbraco logs the following:

• 2018-12-06 12:21:03,276 [8] INFO Umbraco.Web.BatchedServerMessenger [T76/D2] Submitting calls to distributed servers

I do not really understand what this error is about and how to resolve it.
