- TITLE :Unable to Create Sufficient Pagefile with Temporary Pagefile
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- ----------------------------------------------------------------------
-
- SYMPTOMS
- ========
-
- In Windows NT, if you set your pagefile (PAGEFILE.SYS) lower than the
- recommended amount (12 MB plus system RAM), Windows NT may have to
- create a temporary pagefile (TEMPPF.SYS) to operate.
-
- If the temporary pagefile takes most of the free space on your hard
- disk, you may receive the following error message after you log on:
-
- Limited Virtual Memory
- Your system is running without a properly sized paging file.
- Please use the virtual memory option of the System applet in the
- Control Panel to create a paging file, or to increase the initial
- size of your paging file.
-
- CAUSE
- =====
-
- Windows NT displays this error message when the setting in Initial
- Size of the pagefile exceeds the amount of free space on the hard
- disk. This can occur when a temporary pagefile takes the majority of
- free space on the hard disk, leaving less space than the Initial Size
- of the pagefile setting specified in the Control Panel.
-
- This situation can occur when the initial paging file size is reduced
- to an amount considerably smaller than the recommended amount and the
- system is restarted. At startup, the smaller paging file is created,
- the system then recognizes that the size is insufficient and creates a
- temporary paging file of up to 20 MB in the WINNT\SYSTEM32 directory.
- The System dialog box from Control Panel spawns, forcing you to
- address the paging file problem.
-
- When the free hard disk space approaches 30 MB or lower, problems can
- occur in trying to correct the insufficient paging file size. The
- combination of the insufficient paging file and the temporary paging
- file can easily use all the available free hard disk space. This does
- not leave enough free space to create a paging file sufficient in size
- to eliminate the need for the temporary paging file.
-
- The only way to free the disk space used by the temporary paging file
- is to create a new paging file close to the recommended size. Once
- there is no longer a need for the temporary paging file, it will be
- deleted upon the next startup of Windows NT and the disk space will be
- freed.
-
- RESOLUTION
- ==========
-
- To eliminate the above error message, either create enough free disk
- space so a sufficient pagefile can be created, or use the following
- procedure:
-
- WARNING: Using Registry Editor incorrectly can cause serious,
- system-wide problems that may require you to reinstall Windows NT
- to correct them. Microsoft cannot guarantee that any problems
- resulting from the use of Registry Editor can be solved. Use this
- tool at your own risk.
-
- 1. Open the Registry Editor (REGEDT32.EXE) and use the following
- path:
-
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
- Session Manager\Memory Management
-
- 2. Find the following value:
-
- PagingFiles:REG_MULTI_SZ:C:\pagefile.sys X 20
-
- 3. From the Edit menu, choose String.
-
- 4. Replace the first number listed (X) after PAGEFILE.SYS with the new
- initial value of the pagefile size (megabytes used by the TEMPPF.SYS
- and insufficient PAGEFILE.SYS).
-
- 5. Shut down and restart Windows NT.
-
- Because the pagefile setting will now be sufficient, the temporary
- pagefile will be deleted by Windows NT and there will not be Virtual
- Memory errors.
