I've just started using ANTS Memory profiler, and I'm having some trouble working out just what the instance retention graph means. I have managed to use it to identify some memory leaks - mostly events that were not being de-registered. But I have now come across some references in the graph which I cant work out what they are being caused by.
A screengrab of my graph can be seen here: http://www.decezy.com/images/ANTS_Screenshot1.png
I cant work out whats going on here. The FrmJobCard is the form which is not being released from memeory. The UltraCalcManager is an infragistics tool which allows other Infragistics controls to calculate a value, based on other controls. When added to the form, it automatically adds itself to all the controls in the FrmJobCard.Designer.cs.
There are no events associated with it (UltraCalcManager), so there is nothing to unload.
Can someone point me in the direction I need to go? What to look for? Or if this forum is not for this kind of thing, where can I go?
