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.
