This article was previously published under Q195541 SYMPTOMS
A system may leak nonpageable memory when a large amount of mounts and
dismounts are done on an NTFS partition.
CAUSE
The driver Ntfs.sys does not keep track of a VPB structure if a dismount
request is followed by an unlock request. The memory leak is small, so the
problem will usually appear after a period of days. POOLMON can be used to
check this problem. Look for the NtfV tag taking up a lot of the
nonpageable memory. Performance Monitor can also be used to monitor
nonpageable memory use.
