I have a strange issue that appears to have started recently.
When I copy a large file (Approx 6GB) from my laptop to one of our older fileservers the server runs out of memory after a few seconds.
This has only started recently, maybe since patch Tuesday although I can't be sure.
This server is a Windows 2000 sp4 machine, its a Dell 2950 with 1GB ram (Note: I am sure this server had more than 1GB!, I can't physically check until the end of the day when I can power it down), 3GHz Xeon proc, 4 x 250Gb 7.5k RPM SATA drives in raid 10 and a 1 Gigabit NIC connected to a 1GB port on an intel managed switch.
(Apparently I can't post images so a link will have to do)
As soon as I stop the copy the memory instantly frees up:
I've removed the antivirus which made had no impact. I've changed the "File and Print Sharing for Microsoft Networks" options to balanced.
We have another server, Windows 2000 SP4 with 2GB Ram, 2.8Ghz Intel Quad Core, 6 x 300Gb 15k SAS in raid 10.
When I copy the same 6GB file here the amount of available memory doesn't change.
Is there anything else I can look at while the server is running? As it's in use and not really affected by small file copies I can't reboot it just yet.
Here is a screen shot of some perfmon counters I had open just as the server runs out of memory.
