Handle leak in System process?
I mentioned in a prior post that when I did that, the search app crashed
because of the massive number of small files it found. I did what I needed with a Unix command. Thanks CL "Michael W. Ryder" wrote in message ... Questor wrote: About the only way I can think of is to open Windows Explorer and go directory by directory and click on the top of the Size column. This will arrange the files by size and not name. The zero-length ones will go to the top of the list (or the bottom, depending on how many times you click). VERY tedious operation however. I have no idea of knowing if you know, but clicking on the top of ANY column sorts the listings in that order.

Every so often, programs will fail to load and Windows (or an app) will complain about being out of memory or system resources. Or windows won't open. Etc., etc. I've been looking high and low for the reason for this, with little luck. One thing I have noticed is that when the PC starts to get cantankerous, the System process has an elevated handle count (18,500 this last time I started having problems). When I check the System process through Process Explorer, I see thousands of handles open to what looks like an empty key, and a lesser but still large number of handles open to what looks like a file with no name: -------------------- DETAILS Basic Information Name: Type: Key Description: A Registry key References References: 1 Handles: 1 Quota Charges Paged: 0 Non-Paged: 0 SECURITY Unable to display security information. -------------------- DETAILS Basic Information Name: Type: File Description: A disk file, communications endpoint, or driver interface. References References: 2 Handles: 1 Quota Charges Paged: 0 Non-Paged: 0 SECURITY Everyone: Delete, Synchronize, Query State, Modify State, (Special Permissions) Advanced: Permissions: empty Auditing: empty Owner: Everyone -------------------- The Handles list shows all of these empty Key handles with an Access code of 0x000F003F, and the empty File handles with an access code of 0x0012091F. I have checked just about every other process listed in Process Explorer. No other process that has handles open to Registry keys has any open to blank or empty keys. Process Explorer shows valid key names for every other key every other process has open. No other process that has handles open to files has any open to files with no name. Rebooting the PC solves the problem -- temporarily. The System process returns to a manageable handle count. But even after rebooting, Process Explorer shows a collection of "empty" keys and "no-name" files open to the System process. And even with the PC just sitting there at a desktop with no other windows open, that count steadily increases over time. At the risk of sounding stupid: This is _not_ normal, right? How do I find whatever is triggering this, if I don't even know what to look for? Any help would be appreciated. Thanks CL |

... As for 0-length files: I just discovered that there's no way to search for them in Windows XP ... Hi Charles, Here is a simple VBScript to list Zero Byte files: '[Begin Code:] For Each obj in GetObject("winmgmts:\\.\root\cimv2").ExecQuery(_ "Select * from CIM_DataFile where FileSize = 0") Wscript.Echo obj.FileSize & " -- " & obj.Name Next '[:End Code] Copy and paste the code into NotePad and SaveAs: C:\ZeroByte.vbs Open a Command Prompt window (Start|Run CMD) at C:\ Use this command to list files: Cscript ZeroByte.vbs | More That will list the files one screen full at a time, with a More prompt. Press Spacebar for next screen full. Or you can use this command to send the list to a text file: Cscript ZeroByte.vbs C:\ZeroByteList.txt Do not double click the ZeroByte.vbs file, or it will run with Wscript, (instead of Cscript,) and will use the MsgBox feature to display the files one file per message box, one after another when you click OK. To stop that, you have to use Task Manager to End this Process: Wscript.exe Keep in mind that some Zero Byte files are necessary, like those in your "Send To" folder, and some in the root (C folder. Most Zero Byte files are found in your "Temporary Internet Files" (TIF) subfolders, and can be safely deleted. The normal "Internet Options" Delete Files function only gets rid of files that are listed in the [TIF] index.dat file. There are other programs beside Internet Explorer that use TIF for temp files.
