Error after update

The log shows that UPnP Browse requests sent by the control point are being pipelined and multiplexed onto a small thread pool. These are not the cause of the problem.

The problem is caused by HTTP GET requests sent by the control point to download artwork images. These are not pipelined, so the control point is opening a new HTTP connection for each GET request and closing it after MinimServer has responded. The correct way to do this (if it is necessary) is for the control point to open a small pool of HTTP connections and pipeline these GET requests onto this connection pool.

This pipelining needs to be done by the control point. MinimServer cannot avoid the overhead of opening an HTTP connection for any HTTP request that isn't pipelined.

As well as this problem with HTTP connections, another issue is that VLC appears to be "scraping" the server for the entire library including all artwork images. Most UPnP control points (including BubbleUPnP) don't do this but just read those portions of the library that the user has chosen to browse.

It is the combination of all of these factors that is causing memory usage with VLC to expand unmanageably in the way that you are seeing. BubbleUPnP is an excellent control point, well designed and efficiently implemented, and will not cause the memory usage problems you are seeing with VLC.
