I'm using Winstone via the Hudson Build server. It was running fine for a few days... and not heavily used by many people. I had recently moved it to being behind an apache proxy. Somehow I think we're leaking objects.
Here's how I'm starting it:
java -Xmx512m -DHUDSON_HOME=/apps/hudson/ -jar /apps/hudson/hudson.war --prefix=/hudson
[Winstone 2007/05/03 16:02:25] - Error within request handler thread
winstone.WinstoneException: ReqPool: Max requests in pool exceeded - denied
