If Access Violation messages appear in the NetBackup logging, investigate the times to determine whether the image cleanups are running at the same time as image list queries.
The Access Violations will only occur if the image cleanups and image lists are performing actions on the same backup ID/images at the same time. This is a rare race condition which can occur if a busy system, which is running the very frequent and wide date ranging image queries (such as Oracle cross-checks), at the same time when the main image database cleanup is being performed and expiring/removing backup images (by default every 12 hours).
These messages are appearing in the BPDBM log when the combination of an image cleanup is being performed (Q_IMAGE_DELETE) and image queries (Q_IMAGE_LIST_FILES).

The function lock_file_by_path() is defined in common NetBackup library code. The call in the above log extract, created a *.lck file for the specified backup if it does not exist.
In addition, almost all callers of the function lock_file_by_path() sets an argument bDeleteOnUnlock to false. Consequently, unlocking will not remove the *.lck file and it will be left in the images database directory.
The catalog cleanup does remove the *.lck file as the result of call of ImageDelete::expire_image().
The issues occur because it’s possible that different result sets of simultaneous Q_IMAGE queries include the same image.
Cause
A combination of a busy system, and the image database cleanup removing files/images when image list queries of the same image(s) are running simultaneously
Solution
NetBackup is working as designed, this rare condition which could occur and does not cause any problems.
However, Veritas Engineering are aware (Etrack 3441606) and they will try to improve the messages received in the logging to demonstrate the reason for the error.
The plans are to record a the reason for the eror; please see an example below which should appear in the BPDBM log;
00:44:22.802 [43292.12092] <4> db_error_add_to_file: File: ../nbe_cat_c_api.cpp Line: 55: access violation, 00:44:22.818 [43292.12092] <32> Function: CatImg_OpenCatFile: File: ../nbe_cat_c_api.cpp Line: 55: access violation,
00:44:22.818 [43292.12092] <32> POLICY_1387816327_UBAK was deleted. <<<<---Updated entry.
The same situation can occur after the code change. Veritas engineering have scheduled an update for the NetBackup release 7.6.0.4.

First, your user must have administrator permission.
Second, install Xampp outside of "program files", preferably install in C:\xampp (It usually comes with this by default).
Third, after installation (Before running Xampp), go to the C:\xampp directory, look for xampp-control.exe, right click on it, go to "properties" go to the "compatibility" tab and then check the "run as administrator" option.

The problem that the "Symptoms" section describes was corrected in Windows Update Agent 3.0 and in update 927891. These updates were distributed through Microsoft Update in June and July, 2007. If you are still experiencing a problem that resembles the one that this article describes, it may be a different problem. To troubleshoot similar problems, please see the "Similar problems and resolutions" section later in this article.
When you try to install an update from Windows Update or from Microsoft Update, you experience the following symptoms:
-
The system may appear to become unresponsive when Windows Update scans for updates that use Windows Installer.
-
You receive an access violation error in the Svchost.exe process. This process is related to the Automatic Updates service. This access violation occurs when you use Automatic Updates to scan for updates by using the daily automatic schedule or when you visit the Microsoft Update Web site to manually scan for updates.
-
A memory leak occurs when Windows Update scans for updates that use Windows Installer.
-
Windows Update scans take a very long time, sometimes hours, to finish.
To resolve this problem, follow these steps.
To get the stand-alone package for this update, go to the Microsoft Update Catalog website.

Microsoft has released a Microsoft Security Advisory on this problem for IT professionals. The security advisory contains additional security-related information about this problem. To view the security advisory, visit the following Microsoft Web site:
//www.microsoft.com/technet/security/advisory/927891.mspxNote This article discusses the MSI component fixes only. This fix is one component of a two-part fix that includes a Windows Update client software update. These updates will be deployed automatically by using Windows Update in May 2007 and June 2007. However, some customers may select to manually install these updates. To fully address the unresponsive system issue, both this fix for MSI must be installed and the Windows Update client must be updated to version 3.0. When you install the MSI fix and the new client, process-monitoring tools may still show CPU usage at near 100 percent. However, the system should still be responsive and should not lock up. If another task requires CPU cycles, they will be shared. However, if the system is idle, MSI will use the full cycles that are available to complete in the shortest time. If another task is running at the same time as MSI, the system may run slightly more slowly. However, the computer should still be responsive. Remember that you must install the MSI fix and the new client to address unresponsive or locked systems. It is expected that process-monitoring tools may still show CPU usage at near 100 percent, but computer unresponsiveness is expected. If you watch the process monitor, you may still see CPU usage at near 100 percent during some scans if the computer is otherwise idle. This is expected behavior.Important Many instances of the Svchost.exe process may be running on a Windows-based computer. These Svchost.exe processes control certain tasks. The software update that is described in this article is only designed to address the problem that is mentioned in the "Symptoms" section. Other problems that you experience with Svchost.exe may require alternative resolutions or troubleshooting steps.To resolve this problem, you must install this update together with the Windows Update Automatic Client 3.0. The Windows Update Automatic Client 3.0 will automatically be released through Automatic Updates by June 30, 2007. The updated Windows Client changes the thread modeling to move MSI scans to a thread that is separate from the user interface.
For the MSI update, install one of the following updates based on the version of Windows that is installed. To determine the version of Windows that is installed, follow these steps:
-
Click Start, click Run, type sysdm.cpl, and then click OK.
-
In the System Properties dialog box, click the General tab, and then notice the information that appears under System.
After you download the appropriate update, double-click the update package to install the update.
Note All versions of Windows XP, except for Windows XP Media Center versions, state "Version 2002" on the General tab in the System Properties dialog box. The update that is listed in the "Windows XP, all versions (including all versions of Windows XP Media Center)" section is correct for all versions of Windows XP. This includes all versions of Windows XP Media Center.
Note To install the update, you may have to apply the latest service pack for the version of Windows that you are running. For more information, click the following article numbers to view the articles in the Microsoft Knowledge Base:
