Question

Answer 1

+2 A:

You can use the !dumpheap -strings to list strings. Unfortunately this doesn't give you the object references. You can use -min/-max with the -type flag to specify a size to limit the output to strings of a certain size.

SOSEX.dll has a very useful !strings command, that lists both the object reference and the text, so it is easy to locate specific strings. It has built in filtering and supports the min and max length options as well.

the application I'm debugging took 1.41 gb memory (plus about the same amount of virtual memory) and I'm trying to figure out why. having 835Mbs allocated for strings didnt seem normal to me, and I'm trying to figure out what all strings are used for.

Ins't min/max just object size and not object index? (i.e. I want to view objects # 100000 to 100100 of all 441762 objects)

@jgauffin: You'll generally see a lot of strings in any .NET application, but 800+ MB of strings seems like too much. Are you building XML/HTML/whatever documents on the fly perhaps?

Brian Rasmussen 2010-10-05 13:36:47

Yes, min/max are used to specify size. Did I suggest otherwise somewhere?

Brian Rasmussen 2010-10-05 13:38:03

no, you didn't suggest anything else. I was looking for something else, sorry :) The application using a lot of memory is a COM+ application (server application with a lot of ServicedComponents). It's called from a Windows Service and returns datasets (mostly untyped).

Do you have any idea what the strings are at this point? Otherwise I suggest using SOSEX.dll to dig around. Let me know if you have additional questions on this.

Brian Rasmussen 2010-10-05 13:45:56

!strings lists all 441 762 strings, not very useful

jgauffin 2010-10-05 13:53:57

As I said, you can specify a filter, if you're looking for specific strings. Otherwise use the -min flag to find all strings of a certain size.

Brian Rasmussen 2010-10-05 14:38:59

Use !sosex.help strings for a list of options.
