This didn't happen until I started using offline folder sync with a shared folder on my office pc.  Now I get the BSOD intermittently.  Sometimes in 1 minute sometimes in 5 hours.  But it wasn't happening before.

HP Pavilion dv-71157cl laptop upgraded to Win 7 ultimate x64

4gb ram
From the dumps, all bugchecks were caused by an access violation in the context of executing nt!ObAdjustSecurityQuota, at the same offset.  Two had traces of a Symantec / Norton component (SRTSP64.SYS) in the stack.

There are elements of nearing the commit limit.  You don't have a paging file configured, it would seem?

A few thoughts... consider configuring a paging file - say, 2 GB, or a system managed size.  See if that has any impact on the behavior.  (Even if not, a paging file is still helpful despite gobs of RAM.)  Also - check for program updates to the Symantec / Norton software.  (The drivers seem quite old - what version of NIS/NAV are you using? SRTSP64.SYS is from early 2008 and other Symantec components are pre-Win7 RTM.)  If you don't want to purchase an update, uninstall the Symantec software (use the removal tool) and go for another (hopefully lighter-weight) solution.

Something is causing the rdbss.sys to be driven out of bounds. (Redirected Drive Buffering
SubSystem Driver

The three main potential fixes are in order.

1. Update drivers - particularly network/wifi and video

2. Change your antivirus/antispyware/security programs which can be causing or at least
contributing to the error. Includes 3rd party firewalls.

3. Add more memory can sometimes help.

You can view the minidumps yourself with this utility which is small, easy, and free.

This is an excellent tool for posting Blue Screen Error Information so instead of having to
upload the minidumps you can paste the info in a message here as you did above.

BlueScreenView scans all your minidump files created during 'blue screen of death'
crashes, and displays the information about all crashes in one table - Free

Similarly this utility can help to gain troubleshooting information.

MyEventViewer - Free - a simple alternative to the standard event viewer of Windows.
TIP - Options - Advanced Filter allows you to see a time frame instead of the whole file.


References to Vista also apply to Windows 7.

This is my generic how to for proper driver updates :

This utility makes it easy to see which versions are loaded :

DriverView - Free - utility displays the list of all device drivers currently loaded on your system.
For each driver in the list, additional useful information is displayed: load address of the driver,
description, version, product name, company that created the driver, and more.

For Drivers check System Maker as fallbacks and Device Maker's which are the most current.
Control Panel - Device Manager - Display Adapter - write down the make and complete model
of your video adapter - double click - Driver's tab - write down the version info. Now click UPdate Driver (this may not do anything as MS is far behind certifying drivers) - then Right Click -
Uninstall - REBOOT this will refresh the driver stack.

Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party
with their own software and drivers and any other major device drivers you have.

Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device
Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for
BIOS, Chipset and software updates at System Maker's site while there.)

Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT after
each installation.

Always check in Device Manager - Drivers tab to be sure the version you are installing actually
shows up. This is because some drivers rollback before the latest is installed (sound drivers
particularly do this) so install a driver - reboot - check to be sure it is installed and repeat as

Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check
manually by model.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

How to Install a Device Driver in Vista Device Manager

If you update drivers manually then it is a good idea to disable Driver Installations in Windows
Updates, this leaves Windows Updates ON however it will not install drivers which will usually
be older and cause issues. If Updates suggests a new driver then HIDE it (Right Click on it)
and then go look for new ones manually if you wish.

How To Disable Automatic Driver Installation In Windows Vista - Drivers


What antivirus/antispyware/security products do you have on machine? Include any you have EVER
had on this machine including those you uninstalled (they leave remnants behind which can cause
strange issues).

Try removing your present one and use MSE or AVAST. Be sure to use the maker's removal tool and
reboot before installing the replacements - Download them but install after the removal.

List of removal tools

For all as needed use this method :

Download - SAVE - go to where you put it - Right Click on - RUN AS ADMIN

Here is what I use and recommend :

Avast and Prevx have proven extremely reliable and compatible with everything I have
thrown at them. Microsoft Security Essentials and Prevx have also proven to be very
reliable and compatible. Use MSE and Prevx or Avast and Prevx however not all 3.

Avast Home Free - stop any shields you do not need except leave Standard, Web, and
Network running.

Prevx - Home - Free

Windows Firewall

Windows Defender (not needed if using MSE)

IE - Protected Mode

IE 8 - SmartScreen Filter ON  (IE 7 Phishing Filter)

I also have IE to always start with InPrivate Filter active if IE 8.
(You occasionally have to turn it temporarily off with the little Icon on LEFT of the + bottom
right of IE)

Two versions of Avast are available 5.x and 4.8x

Avast 5.x - Home - Free - Stop the Shields you do not use (except File, Web, Network, &
Behavior) - double click the Orange Icon in Notification Area - Real Time Shields - click the
Shield you want to stop - STOP. To stop the Orange Icon from showing an error indicator -
click the Orange Icon - Upper Right - Settings - click Status Bar - uncheck the Shields you
disabled - click OK

Avast 4.8x - Home - Free - stop any shields you do not need except leave Standard, Web,
and Network running. (Double Click Blue icon - details next to OK. - upper left Shields -
Terminate those you do not use.)

Or use Microsoft Security Essentials - Free

Prevx works well along side Avast or MSE

Prevx - Home - Free small, fast, exceptional CLOUD protection, works with other security
programs. This is a scanner only, VERY EFFECTIVE, if it finds something come back here
or use Google to see how to remove.   <-- information  <-- download

PCmag - Prevx - Editor'a Choice,2817,2346862,00.asp

Also get Malwarebytes - free - use as scanner only. If you ever suspect malware, and that
would be unsual with Avast and Prevx running except for an occasional low level cookie
(no big deal), UPDATE it and then run it as a scanner. I have many scanners and they
never find anything of note since I started using this setup.


Sometimes adding more memory can help with this issue.

Hope this helps.
