Thanks, that was really helpful. If you took the time to visit the archive to be able to reply to me that this was answered already I might have expected you to post the URL.
I have actually checked the archives already and there is no such post as far as I can see that addresses the particular precise question I am asking. Just because you can type in "windows task manager memory" and get back lots of results does not mean that my question is answered since the search engine seems to OR the search terms. Anyway that's by the by. I have detailed a precise situation relating to the WTM view and the heap view in JProfiler. I asked a similar question a while back but never got a completely satisfactory reply which is why I ask again. If of course this precise question is answered on the arhives I apolgise very much and would appreciate the URL.

This topic has been discussed on the list at least twice this year in very much detail. cu Steffen -----Original Message----- From: Allistair Crossley [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 09, 2004 5:46 PM To: [EMAIL PROTECTED] Subject: Heap View vs Windows Task Manager I wonder if anyone on this list can once and for all make me understand the difference between the Windows Task Manager process memory and the Heap View in such a program like JProfiler. My Windows Task Manager reports on first loading my application about 50MB. As I wander around it grows until eventually at 158MB I get OutOfMemoryException. The intriguing thing to me is that in the Heap View of JProfiler which I look at AT the same time as the WTM never reports anything over 15MB!! The free heap size stays at 15MB and the used heap size always shows spikes indicating garbage collection but it keeps under the 15MB. When it first starts the free heap is 10MB and in this case the free heaps grows to accomodate the required heap but 15MB seems to be the max it ever goes to. So why on earth does my WTM report onwards to 158MB and bail out? Would so very much love a clear understanding of this and I see others asking similar questions so I think it could be of use to the broader Tomcat list Thanks to he who undertake this question!
