NOTE: The parameter values may be different on your computer, but a memory analysis in a dump file indicates that the error messages are based in either the Qafilter.sys or Qsfilter.sys files.

CAUSE

This behavior may occur if all the following conditions exist:

The WQuinn "QuotaAdvisor" or Northern Parklife "Quota Server" disk-quota-management programs are installed on your computer.
The driver file for the quota management program is outdated.

NOTE: The driver for QuotaAdvisor is Qafilter.sys, and the driver for Quota Server is Qsfilter.sys.

RESOLUTION

To troubleshoot and resolve this behavior, remove or disable the quota-management program to verify that the program is the cause of the STOP error messages, and then contact the program vendor to inquire about the availability of an update that may resolve this issue.
