I’ve got some strange error messages showing up in some of my logs and I’m not sure what they mean or how to deal with them.

First some background: I’m running a load balanced origin/edge configuration. The number of edges running varies with load - when the current set of instances approach their configured maximum, more workers get spawned to keep up with the load. At his moment I’ve got 30 workers running.

In tracking down an issue we experienced last night I happened to notice log lines that look like:

_Aug 7 15:50:55 ip-10-190-81-99 wowzaAccess: 2012-08-07 15:50:54 UTC comment server WARN 200 - CommandInterface.messageReceived: Message authorization failed. - - -736892.691_I don’t get huge numbers of them. For example, last night while I had 30 instances running I get:

_[root@db2 ~]# grep “CommandInterface.messageReceived: Message authorization failed” /wowzalogs/wowza.log-20120807.\* | awk ‘{print $4}’ | sort | uniq -c_

_4 ip-10-4-38-119_

_4 ip-10-46-9-165_

_4 ip-10-46-94-107_

That’s 12 instances out of 30 logging those messages, either 4 or 8 lines each.

What do those log lines mean?

What was the issue you were tracking down?

It might help to remove or comment out the /conf/Server.xml /CommandInterface
