By the look of it, something in OpenSim is failing to close connections.  After 24 hours, the HttpServer embedded in OpenSim eventually finds that it runs out of sockets to play with.

I'm surprised to see this in standalone mode.  Are you doing something with OpenSim in standalone mode that requires outbound connections (e.g. remote database, groups, etc.), or perhaps a script that regularly establishes an outbound connection?  

If this has just started crashing after being fine before then it suggests that something has changed locally to reveal a bug in OpenSim.
