I tried to use 'webrick' (not thin), same results (actually the overall memory footprint went down from 140MB (thin) to 32MB (webrick)).

> Deltacloud API memory usage is slowly increasing after doing 100+ requests:
> Starting Deltacloud API :: mock :: http://localhost:3001/api
> >> Thin web server (v1.5.0 codename Knife)
> >> Debugging ON
> >> Maximum connections set to 1024
> >> Listening on localhost:3001, CTRL+C to stop
> 127.0.0.1 - - [17/Oct/2012 15:26:10] "GET /api/images HTTP/1.1" 200 4420 0.0308
> 127.0.0.1 - - [17/Oct/2012 15:26:17] "GET /api/images HTTP/1.1" 200 4420 0.0220
> 127.0.0.1 - - [17/Oct/2012 15:26:52] "GET /api/images HTTP/1.1" 200 4420 0.0219
> ... 1000 requests after:
> 127.0.0.1 - - [17/Oct/2012 15:27:53] "GET /api/images HTTP/1.1" 200 4420 0.1539
> 127.0.0.1 - - [17/Oct/2012 15:27:53] "GET /api/images HTTP/1.1" 200 4420 0.1554
> 127.0.0.1 - - [17/Oct/2012 15:27:53] "GET /api/images HTTP/1.1" 200 4420 0.1526
> As you can see the response time is slowly increasing and after few minutes it gets to the point where the request take like 10 seconds to complete and all your free memory is gone ;-)
> This is easy to reproduce:
> 1. Start Deltacloud API ($ deltacloudd -i mock)
> 2. $ while true; do curl -H 'Accept: application/xml' --user 'mockuser:mockpassword' http://localhost:3001/api/images > /dev/null; done
> 3. Keep it running for ~1minute and watch the console with Deltacloud API log.
> Thanks to Tomas Hrcka for reporting this.
