We have been getting this problem on a couple of our NW 6.5 SP6 severs
lately. They are both HP Proliants, different models though.

The server will go down to a text screen that says the following:

Unable to EXEC server (insufficient memory?).
Cannot load the file C:COMMAND.COM
Insert correct disk and Strike any key

When I bring the server back up I notice that it had an ABEND.
"Deadlock detected waiting for spinlock currently owned by CPU00"
"Running Process: Server 00"

Any suggestions?
