Windows 2000 Server Memory Limits

[ykc73]

Hi,
We are running our application on a dedicated windows 2000 professional server with 3.5 gig physical memory and 4-6 gig virtual memory. But when the application is loading data and the memory crosses the 3 gig limit, our application crashes with "not enough memory" error. Is there any limit for application running as user application or as a service with a 3 gig memory usage limit? Any help is greatly appreciated

Thanks
Kalyan

I believe the switch /pae in the boot.ini file will fix that. Make sure to backup your boot.ini file first, and probably add another entry.

Instead of this...

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect

Try this...

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional PAE" /fastdetect /pae

Be aware that the switch only works with

Win2000 Advanced Server
Win2000 DataCenter Server

Can you clarify which OS this is for? You specify Windows 2000 Professional Server...it probably isn't.

Thanks for all your responses.
We are running our application on a "Windows 2000 Server" and we tried on 2 machines wiht 2.3 GB and 3 GB RAM but upto 6 GB Virtual memory and on both machines, it crashes after it cross the 3 GB limit

Sorry, 32 bit os = 4GB address space

With your OS you have a 2GB Ram limit....
You will have to check to see how far you can go with virtual memory ....

Win2k can access more than 4gb with PAE.
