BIG file copy problems: WORKING_SET

Hi Folks,

We have the following scenario:

- Windows 2003 Enterprise x64, SP2
- HP DL585
- Opteron 2.2Ghz CPU, ~25% average
- 8GB RAM, ~40% free
- SQL 2005
- Gigabit LAN


As part of backup procedures, we use SQL Manager to create a daily database
dump, wich is ~40GB in size. This big file is then copied across the LAN to
another server running W2k3.



Each ~2 days the server stops responding at random during the copy
operation, requiring a reboot. The following message appears:



"Cannot copy daily_dump.bak: Insufficient quota to complete the requested
service"



After checking *disk* quotas and network configuration, nothing abnormal was
found. Diggin' deeper into MS Support Site and Google, we've found that the
problem is not related to "disk" quotas, is related to Windows' "Working Set"



------------------------------------
Windows Error 0x000005AD - 1453
Insufficient quota to complete the requested service.
ERROR_WORKING_SET_QUOTA
------------------------------------



We are unable to proceed with daily tasks. Tape backup is already part of
the internal policy, but we need to copy this file over the LAN.



Any help and insight will be *vastly* appreciated.
