    <p>I am launching many threads simultaneously, each one writing / reading data into/from a queue; Data is dequeued progressively while it is processed and stored to DB. For some reason <strong>the memory is not freed</strong> although the Queues are empty and I made sure all event subscription between the data reader and the data processor are unsubscribed at the end of the threads.<strong>The amount of squatted RAM is <em>Exactly</em> the amount of the data that is read</strong> by binary readers and put into queues.</p> <p>In order to isolate the problem, I have bypassed the Processing and the DB Storing step. <br>Why would be the RAM still squatted long after all threads are finished, <strong>until I explicitly call <code>GC.Collect()</code> or terminate the program</strong>? I manually nullified the Queue after it is emptied, and also nullified the Binary Reader that read the data. I thought that would be enough for the GC to wake up and do its housekeeping at least after a few minutes.</p> <p><img src="https://i.stack.imgur.com/yOi9b.png" alt="enter image description here"></p> <p><strong>EDIT :</strong> <strong>The (reformulated after deletion) QUESTION :</strong> In short, I was always told that the default GC behaviour managed the memory properly and that I shall almost never call the GC explicitly and let the framework do the job.<br> I would like to know why in this case memory usage drops down only when an explicit Call is made to <code>GC.Collect</code></p> <p><strong>EDIT : <br>Without GC Collect</strong> <br> <img src="https://i.stack.imgur.com/G6mNj.png" alt="enter image description here"></p> <p><strong>With GC Collect</strong> (Called on a regular basis) <img src="https://i.stack.imgur.com/tiiYG.png" alt="enter image description here"></p>

    1. COYour problem can be related to many things, without taking a look into your code is quite hard predict why GC is not using the broom, if you want we can use VS Anywhere to review the code together...

    3. COYou seem like a pretty clever person thats quite animated, but you do have trouble staying on topic. The last part of your post is "The Question: ...." followed by a funny rant with no direct question. Although I think you already nested your question earlier in your post

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
