The CMS collector, which you have turned on, needs lots of memory. If the CMS collector ever gets behind in cleaning the tenured generation of the heap, a very expensive "stop the world" collection takes place. I once forced the CMS collector to get behind on a particular app and the garbage collection took around 5 minutes (using the standard collector a Full GC on that same app takes about 2 seconds).
Also, do you have only one CPU? Never use the CMS collector when you have only a single CPU. Of course, without gathering any GC data, it is all speculation. What data have you gathered so far?
