SYMPTOMS
When an extended attribute stream is flushed, the Cache Manager and the Memory Manager may become deadlocked and may stop responding if they try to flush the stream at the same time. The following event ID may be reported in the system event log:

Event Type:       Error Event Source:     Srv Event Category:   None Event ID:         2020 Date:             6/21/2001 Time:             6:06:19 P.M. User:              N/A Computer:         computer_name Description:      The server was unable to allocate from the system paged pool because the pool was empty.

Note that a 2020 event ID is a common event ID that could occur with other situations and does not necessarily indicate that you are encountering this issue.



CAUSE
This behavior can occur when you have files that have a large number of extended attributes(An example of a extended attribute is the list of items under the summary tab of a file properties box). The NTFS file system does not assign the extended attribute streams a paging I/O resource and does not mark them as modified-no-write.
