The Exchange 2000 Jet engine may log 1450 errors when it attempts to extend a log file.
Microsoft Windows 2000 may run out of kernel resources (PTEs).
NOTE: Having the /3GB switch on makes this considerably more likely.
Windows 2000 fails large I/Os because it cannot allocate enough memory in the kernel. This affects all processes on the server. When Jet encounters these errors, it reduces the size of its I/Os down to as low as 4 kilobytes (KB). Jet often uses 1 megabyte (MB) I/Os because that is the fastest way to extend a file under Windows.
