We upgraded one of our NetWare 6.0 sp 5 servers to NetWare 6.5 sp 4a 1 and
1/2 weeks ago, this past weekend (and again last night), it crashed. When
you get to the console, the screen simply says:

Unable to EXEC server (insufficient memory?)
Cannot load the file C:\Command.com

This is our 4th server to be upgraded and the first to encounter any
problems. It is an HP ML370.

When it went down last night, there was nothing written to the abend.log.

Any ideas?
