browser hang (no response) after 3 screens viewed.

[mikesw]

Hi,

I have Win 2K Prof Sp4 with all the latest patches. I have IE6sp1 with all the latest patches.

Connection speed T1. I have all the latest XmlCore v3.0, v4.0 and v6.0 install/patches that

IE may need.

Problem:

When I view about 2-4 web pages, the browser will just stop updating from page 4 onward.

The task manager says "No Response" in the applications window or the IE browser entry for this screen

just disappears from the task manager application window list. If I wait about 3-5 minutes, the

browser will start responding again. Then after about 2-4 web pages, the problem continues again.

Variation #1

If a web page pops a web page window, these popped windows will never finish updating and

will be blank until it times out saying it can't display the page. When windows are popped like this

it speeds up the original window to hang. It seems after about 2-4 window pops, everything

shows up as "no response" or disappears from the task manager application list.

Variation #2

During the time the above hang variations are occuring, I can click on the IE shortcut on the

desktop to start another browser session, and have no problems viewing web pages while the

first session is hanging. Then after about 2-4 web page views on the 2nd browser session, it gets

the same problem. Thus, I click on another browser session to repeat the above scenario.

Opinion:

It seems that the browser/operating system is having memory leak problems somewhere

or that it is performing memory garbage collection. I'm not sure.

Question:

Anyone see this on their system? Do you have a solution? Is there some exe, dll, etc file

I'm missing or patch that will clean this up? It sure is slowing down any productivity on

this PC.

Not sure, but if you can get me a process dump of iexplore.exe when this is occurring I can probably tell you what's happening.

First, install the "Debugging Tools for Windows" from:

http://www.microsoft.com/whdc/devtools/deb...installx86.mspx

Once these tools are installed, do the following:

1. Create a directory called c:\adplus

2. Open a command prompt and change to the directory where you installed the debugging tools. By default, this is "C:\Program Files\Debugging Tools for Windows"

3. Open IE and reproduce the problem

4. Type the following command in the command prompt:

cscript adplus.vbs -hang -pn iexplore.exe -o c:\adplus

This should generate a hang dump of iexplore.exe in C:\adplus, that can be analyzed via windbg or cdb. If you don't feel comfortable doing it, I can do it if you PM me.

Full Windows debug tools website path.

http://www.microsoft.com/whdc/devtools/deb...installx86.mspx

After running this tool. Should I PM you and send the zipped file to you?

Moreover, should I download any symbol file to go along with the debug tool?

[mikesw]

I renamed the dmp file to "pid.dmp"

I ran "cdb -z pid.dmp" and here is the listing I got.

Can you do the following for me?

1. Please add the following system environment variable to your system

Variable Name: _NT_SYMBOL_PATH

Variable Value: SRV*c:\websymbols*http://msdl.microsoft.com/download/symbols;c:\websymbols

2. Create a folder on your C: drive called websymbols (c:\websymbols)

3. Open the dump via windbg, and run the following commands:

!analyze -v

~*kb

Paste the output here, because what you've posted thus far tells me nothing. I need to know what was calling into ntdll, and what called that, etc...

Uninstall the google toolbar, and the problem will likely go away. It's doing a register server in the registry, and then it looks like it's talking to google's servers, and we are pending the toolbar's response (and it hasn't responded yet). IE traffic will likely fail (and possibly other network traffic on the box as well) until the pending register server request finishes (which it doesn't appear that it will), and thus removal of the toolbar should clear this up. Ultimately a reinstall of the latest version may make the toolbar work properly again.

Google toolbar vs WeatherStudio toolbar?

Thanks. I'll try removing and reinstalling the toolbar.

I'm wondering how you could tell it was the Google Toolbar vs. the other

toolbar called WeatherStudio?

I realize that "googleToolbar" appeared

first after the "Exception Analysis" header in the dump followed by the debugger

complaining about the symbols and then the WeatherStudio.dll toolbar message.

Is the ordering above how you could tell?

Moreover, the header error message about the "debugger symbols not being the

correct version" a problem? They were the ones to come down. Moreover, how

would I correct this?

The stack dump only showed a connection stuck open which I assumed time outs

after 5 minutes and then the browser will show can't display page with a ServerInfo "getconnection".

What does "Fsm" mean?

I'm wondering how you could tell it was the Google Toolbar vs. the other

toolbar called WeatherStudio?

I do not see the WeatherStudio toolbar doing anything in this dump other than load, although anything's possible with toolbars. I'll explain a bit on why I believe it's not the WeatherStudio toolbar below.

I realize that "googleToolbar" appeared

first after the "Exception Analysis" header in the dump followed by the debugger

complaining about the symbols and then the WeatherStudio.dll toolbar message.

Is the ordering above how you could tell?

Well, yes, actually, it helps quite a bit. The symbol file errors don't tell me what caused the problem, although they do tell me what was loaded inside the process that the debugger was unable to match to symbols from the Microsoft symbol server (i.e. what 3rd party .dll's are running in the process). Also, dumps are read from the bottom up (the lowest thread is the oldest, and the highest thread is the newest) - and in this case, the thread I see with an open connection pending is running something in "googletoolbar1", or googletoolbar1.dll, and it is in the newest (in this case, also the active) thread, thread 0.

Moreover, the header error message about the "debugger symbols not being the

correct version" a problem? They were the ones to come down. Moreover, how

would I correct this?

Without private (Microsoft internal) symbols for some of these, you don't. And you'll not resolve non-Microsoft symbols (like googletoolbar or weathertoolbar) without adding those yourself, either. This is not a concern.

after 5 minutes and then the browser will show can't display page with a ServerInfo "getconnection".

WININET!CServerInfo::GetConnection_Fsm+0x325

Basically, a WININET!CServerInfo::GetConnection_Fsm call is a chained function for wininet on 2000 SP4 w/IE6 SP1 and XP SP1 (it's a call that actually does 4 functions - these are all documented on MSDN, btw):

1. EnterCriticalSection

2. CServerInfo::KeepAliveWaiters

- This is actually two more functions within wininet.dll itself:

a. EnterCriticalSection

b. LeaveCriticalSection

3. LeaveCriticalSection

4. GetCurrentThreadId

What we see, now that we know what that call actually does, is that the googletoolbar1.dll module has actually initiated a connection with a remote server (via wininet, because we're in the IE process space), and we're waiting on it via kernel32. So, either we'll get a response back from the remote server, and the thread will continue, or we'll timeout and the thread will die. There's no way to know if this will be fatal for the IE process or not, but it doesn't matter - there's no reason for a toolbar (or any other add-on) to hold a connection open like this.

[mikesw]

Thanks for the info.

The following also shows googletoolbar in the stack trace.

I missed this when I read the dumps.

WARNING: Stack unwind information not available. Following frames may be wrong.

I removed the googletoolbar and the 3-4 page views before halting disapppeared. Then

I got 12-15 page views before halting again. I then removed the weatherstudio toolbar

and all the problems went away. Moreover, the browser has signaficantly sped up for

page views. I then updated from googletoolbar 3.0.131 to 4.x and the browser is still working.

I haven't reinstalled the weatherstudio toolbar from v3.3.0 to v4.x since alot of the features it has I don't

need anymore since googletoolbar does most of them. So I guess MSoft made some changes

within the last 6 months with the patches that breaks these older toolbar versions thus requiring

an update.

[cluberti]

That is very possible - glad to hear you got everything working again

[LuckMan212]

hi cluberti i've got similar situation to mike above- I'm getting some hangs in iexplore.exe and am trying to debug it using WinDbg as you've laid out above. I've gotten about 70% through the process but I am kind of stuck on knowing how to make heads or tails of the call stacks. I sent you a PM, do you think you might be able to take a look at my .DMP file if I posted it for you?

[cluberti]

Sure, just upload them and point me at the location, and we can look.

[LuckMan212]

ok, I've zipped up the dump folder and uploaded it:

http://drop.io/4avkcl0

I got your PM about trying to debug a 32bit app with a 64-bit debugger doh!

I am downloading the 32bit WinDbg now, let me give it another go...

[LuckMan212]

whoops-- I've gone and uploaded the wrong dump file.

please dont download that one.

I'm sending the correct one now.
