Process handle leak

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am having a strange problem:

A program running on one computer (dell touch screen tablet) is leaking handles of type Process (as seen both on Process Explorer and Handle ).
The same exact code running on another dell laptop (not a tablet) has no leaks whatsoever.

It doesn't matter if I run the code from devenv or from the executable itself.
It doesn't matter if I compile the code on this tablet or on another computer.
I still only get the process handle leaks on the tablet (to the point where I get a blue screen).

The one thing I am most confused about is that when I look in Process Explorer, I can see that the process handles are all for the same process - the name of which is the application I am running. There is only one instance of this application on the computer.

Any ideas ?!

	Since there have been no replies, let me ask a simlper question. Here is the output from running Handle.exe on my application: =================================== Handle v3.42 Copyright (C) 1997-2008 Mark Russinovich Sysinternals - www.sysinternals.com Handle type summary: Desktop : 1 Directory : 3 Event : 315 File : 79 IoCompletion : 6 Key : 50 KeyedEvent : 1 Mutant : 30 Port : 11 Process : 99 Section : 17 Semaphore : 31 Thread : 20 Timer : 3 Token : 1 WindowStation : 2 WmiGuid : 1 Total handles: 670 =================================== It's the handles of type "Process" that are leaking (quite rapidly). My question is - what exactly is a handle of type "process"? Extra bonus for the answer to the question - what creates or how are these handles created? thanks, Amit.

	does your program create / start other processes? a common source of process handle leaks is the creating process not closing the process and thread handles returned in the PROCESS_INFORMATION struct passed to create process what does procexp tell you the process handles are for?

	Did you ever get any answer to this problem? We are having the same problem with a program here where I work, where it shows up on certain computers, and not on others. If you ever figured out what this was, I'd really like to know! Thanks, Tim
