Hi Eduardo, It sounds like you might benefit from using Appstats. I've heard Java apps tend to have large startup times. However, from what you're describing it sounds like your app is getting new instances spun up (16 in total) but it is not serving requests quickly enough. At least if I understand the issues correctly.
http://code.google.com/appengine/docs/java/tools/appstats.html When you say 'undeploy' the application, you mean you lose an instance? As in you go from, say, 16 to 15 instances? Also what Geoffrey said is correct (of course ;), only active instances are listed. Instances can be spun up and down at any time. Do you see lots of loading requests in your logs?
