O/S-Error: (OS 1450) Insufficient system resources exist to complete the requested service.

Environment information:
Windows: 2000 Server SP4 (incl. Hotfixes KB823980 & KB824146)
Oracle: 32Bit
SAP R/3: (Kernel: 620, DB Client Lib: OCI_817_SHARE, Kernel Patch Number: 1826, SourceID 0.1826, DBSL Patch No.: 1266)
SAP DB Version: 610, 620

Error Message:
"KCF: write/open error block=0x4a8de online=1
error=27070 txt: 'OSD-04016: Error queuing an asynchronous I/O request.
O/S-Error: (OS 1450) Insufficient system resources exist to complete the requested service."

Symptoms: Environment operates fine for a while and then halts with error information above. Problem is intermittent.

I'm not an Oracle or SAP resource, would appreciate some assistance. Have looked at KB304101. I'd like to know whether anyone has experienced these problems before, and whether the solution provided in this KB article resolved the problem. Otherwise, any suggestions on how to resolve this issue would be greatly appreciated.

1. You have SafeGuard Easy installed

SafeGuard Easy Version does not support the asynchronous I/O.

2. The product set for this error stack at the time was an EMC Disk Pack and
  EMC Symetrics Switch. It seems that some I/O devices can speek SCSI 2 or SCSI 3 equally well.

  EMC devices fall into this class of hardware.

  So when the devices started getting these odd errors they were miss-configured
  as SCSI 3.  Windows platforms do not talk SCSI 3 with any proficency.

  Switch it back to SCSI 2 and the import and RMAN restores
  proceeded without failure.
