I/O error 1450(Insufficient system resources exist

Hi,
We're experiencing the following error on a frequent basis
recently - "I/O error 1450(Insufficient system resources
exist to complete the requested service.)"
We are running SQL2000 with AWE memory configured for 6128
MB, with a machine equipped with 8 GB on Windows 2000.
We are also using a SAN. The databases are from 5 GB to 80
GB in size for decision support applications.
Unfortunately, I don't see any events stating that a disk
controller has failed, or anything hardware related.
Does anyone have any suggestions?
Thanks.
Larrylarry, we are experiencing the same problem. did you get yours done?sql
