DOCUMENT:Q166571 09-AUG-2001 [winnt] TITLE :Creating an SFM Volume on Large Partition Causes a Stop 0x24 PRODUCT :Microsoft Windows NT PROD/VER::4.0 OPER/SYS: KEYWORDS:kberrmsg kbWinNT400sp4fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 - Microsoft Windows NT Server version 4.0, Terminal Server Edition ------------------------------------------------------------------------------- SYMPTOMS ======== Shortly after you create a Macintosh volume on a partition larger than approximately seven (7) GB with a large number of files, the system may crash with a STOP 0x24 error in NTFS_FILE_SYSTEM (NTFS.SYS). CAUSE ===== The AppleTalk protocol driver Afp.sys, depletes the memory pool allocated to non-paged pool while indexing a Services for Macintosh (SFM) volume. This problem may also occur when the Services for Macintosh (SFM) server is experiencing performance problems, Event ID 12053 errors, or indexing problems. See the following Microsoft Knowledge Base articles for more information: ARTICLE-ID: Q136300 TITLE : Event ID 12053 or 12054 Caused by Macintosh Client Disconnect ARTICLE-ID: Q147909 TITLE : Troubleshooting MacVolume Creation Errors RESOLUTION ========== To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base: Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack For your convenience, the English version of this post-SP3 hotfix has been posted to the following Internet location. However, Microsoft recommends that you install Windows NT 4.0 Service Pack 4 to correct this problem. ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/NT40 /hotfixes-postSP3/sfm-fix/ NOTE: The above link is one path; it has been wrapped for readability. To work around this problem, increase the non-paged pool memory available to kernel or reduce the number of files on the SFM volume. The amount of non-paged pool available to kernel is a fixed value that is based upon the total RAM in the system. If you increase the RAM you will increase the non- paged pool available to kernel. MORE INFORMATION ================ This problem will generally only occur on a partition with 100,000 or more files that take up 7 to 8 GB or more disk space. When a SFM volume is created, the service will start indexing the partition. The indexing routines create memory structures that consume a large amount of non- paged pool memory and if your volume is large enough and has enough files, you will run out of non-paged pool and the system will stop responding. In most cases, this results in a STOP 0x24 in NTFS, although it can occur when another kernel-mode driver attempts to allocate resources that require non-paged pool memory. The system may simply be slow and unresponsive for the first 20 to 40 minutes after creating the Macintosh volume. This is because of the large amount of kernel memory being used by SFM. If SFM is able to complete the indexing without running out of non-paged pool memory the memory will be freed and the system will return to normal. There should be no problems after this unless enough changes occur that a full re-indexing is necessary. In this case, SFM will have to repeat the procedure. The simplest way to identify this problem is to run Performance Monitor after you create the SFM volume and watch the Memory\Pool Nonpaged Bytes counter. If a constant increase in non-paged pool bytes occurs over a 20 to 30 minute period of time, resulting in large amount (20 to 30 MB or more) of non-paged pool, you may be experiencing this problem.
