Has anyone else noticed NetConnection instability with 5.0.8?

I recently upgraded to 5.0.8, and I noticed instability with NetConnections.

I publish streams from a flash client to AMS over rtmp/rtmpt over port 1935, 80, and 443.

After I upgraded to 5.0.8, I can no longer publish streams longer than a minute. I get NetConnect.Connection.Closed errors. This doesn't happen on the 5.0.7 servers.

Is this a bug, or did I miss something/something got reset during the installation?
