Hello,I am running ..

- winXP sp2, automatic updates
- visual studio 2005, sp1.
- large native C++ multithreaded project, with
about 1500 files, 24 projects. large resource files.
- Dual core pentium 3.2G, 2GB ram
- Whole Tomato visual assist addin

I am finding that the debugger is locking up frequently - sometimes as often as every second time I attempt to debug. With no breakpoints, the system does not lock up. With a breakpoint added I get intermittent lock ups.Sometimes I can debug just fine, other times the IDE and application will both lock up at the same time - at the same breakpoint.

During the lock up - task manager indicates that CPU usage is low. Switching to devenv leaves a white unresponsive rectangle on the screen. The only possible course of action after a lock up is to use task manager to kill devenv.exe.

This problem has occurred within the last month. It has also occurred almost simultaneously on multiple development machines within the company. It has also occurred simultaneously on my home machine and my office machine. This leads me to believe that the problem may be due to ...
- an automatic update, or ....
- the large project has grown to a point where something in it is too "big",
(e.g. # of files, # of lines, size of symbols, size of resources, etc) ... or
- the application is doing something to induce the lock ups.

Sometimes other windows within the system also lock up - e.g. explorer, internet explorer. Sometimes not. Sometimes the entire windows GUI locks up as described in this blog (not me) id=118
I have tried the workarounds in the above blog to no avail.

Appreciate any advice or suggestions. Will be happy to perform any tests or logs or workarounds that you think are necessary.

I have noticed some 5-10 seconds lockups in the break mode on IDE.
Simply clicking on some part of code causes the IDE lockup for a couple of seconds even if I don't change anything....

I've had this same problem, but my project is far smaller than yours.

Have you found a solution or workaround for this

There are varied reasons why stepping can be slow or hangs can occur. Therefore, I doubt that each of you is experiencing the exact same problem. That being said, please take a look through the Debugger FAQ at the Performance section (It has been updated recently). If it doesn't feel free to post more details about what you've tried.

I began experiencing these same symptoms sometime in the last 2-3 weeks.

The symptoms I experience are as follows:
The debugger is stopped at my breakpoint and when I press F10 to step, my mouse cursor changes to an hourglass. After this, all screen redraws are so slow, as to appear to be locked up solid. I know CPU usage is low because my cooling fan runs at a slow speed and once or twice I have been successful in getting Task manger up (after VERY LONG waits of about 1-2 hours). I also see disk activity occurs occasionally.

I can still move the mouse, CTRL-ALT-DEL occasionally will brings up Task manager (after 30 minutes +), but it doesn't usually draw completely, ALT-TAB brings up the task switcher, but redraws are so slow it never completes the task switch. IF I am able to get the start bar to eventually pop up, the time it displays is as much as 30 minutes behind.

When this occurs (many times a day), I have to hard power down by pressing and holding the power button.

I have gone through a shutdown by a quick press of the power button. I went through a series of 'Waiting for XXX to shutdown" dialogs. On each one, I chose to kill the process. When it finally got to devenv.exe and it was killed, the system then quickly finished the shutdown process without further intervention.

I am developing a relatively small c++ console application compiled with CLR support.
(about 12 source files and associated .h files, including one DLL library).

I have been running Visual Studio 2005 for a long time:

Visual Studio Express C++ - since shortly after release
Visual Studio Standard - about 10 months
Visual Studio Professional - about 2 months

Visual Studio Version Info:

Microsoft Visual Studio 2005

Windows XP info:

System Info:

I use the language bar all of the time because I need to be able to enter chinese characters

I have tried un-installing Visual Studio and associated applications and then re-installing but it has made no difference.

Other than Windows updates, I can't think of any major changes to my normal usage patterns. In fact, this is the same project I have been developing/debugging successfully for over 1 month.
