"Stop 0x0000007" Error Message Because of a Memory Leak in the Daprotim.sys File

This article was previously published under Q293857
You may receive the following STOP error message:
STOP 0x0000007a (0xc02882bc, 0xc000009a, 0xa20afeb4, 0x58fd7880)KERNEL_DATA_INPAGE_ERROR
The following second parameter is caused by a lack of non-paged pool:
Event ID 2019 may also be logged in Event Viewer.
There is a memory leak in non-paged pool when you are using the Daprotim.sys file. The pool tag is DAP4. Daprotim.sys is a 3COM Dynamic Access Miniport Server Software kernel-mode driver.
To resolve this issue, contact 3COM to inquire about the availability of a fix for this issue.
To determine is your computer is experiencing this memory leak:
  1. Use the GFlags utility to enable Pool Tagging.
  2. When the computer generates an error message on a blue screens for lack of non-paged pool, load the Memory.dmp file in the debugger.
  3. Run the !vm command to confirm the non-paged pool is exhausted:

  4. Use the kdex2x86 extension to dump non-paged pool, and then select a non-paged pool memory address to sample. In this example, 81457000+8000 (which is 8145f000) was used:

  5. Run the !pool 8145f000 command on the sample.
  6. Confirm through several samples that the DAP4 tag is consuming non-paged pool.
  7. Run the !drivers command to confirm the date of the driver:
