If there is a memory manager in the server, NetWare relies upon the
memory manager to determine the amount of available memory instead
of registering the memory itself. Some memory managers cannot
recognize more than 64 MB of memory. DOS device drivers take memory
away from NetWare’s memory pool.
Make sure Windows 95 is not being used to boot the server. Windows 95
autoloads memory managers.
2 Make sure the server BIOS is current.
An out-of-date BIOS might be reporting the wrong amount of memory.
Update the BIOS if a newer version is available.
3 Verify that the setting for the Reserved Buffers Below 16 MB SET
parameter (Memory category) is set at 300 or higher.
For older drivers, increase the value to 300 or higher, especially if there
is a CD-ROM or tape device that needs memory below 16 MB.
4 Make sure memory is being registered automatically.
Manually registering memory can cause memory fragmentation. Some
old system boards might require you to register memory manually, but the
better solution is to upgrade to a newer board so that NetWare will register
the memory automatically.
If memory has been registered manually, reboot the server to free memory
and do not manually register memory again. Upgrade the system board if
necessary.
5 Verify whether memory errors occur when a traditional volume is
mounting.
If yes, the server might be low on memory.
To free memory temporarily, see “Freeing Server Memory Temporarily”
on page 139. To solve the problem, add more RAM.
6 Verify whether the “LRU sitting time” (in NetWare Remote Manager or
MONITOR), average is more than 15 minutes during peak work hours.
If no, the server might be low on memory.
To free memory temporarily, see “Freeing Server Memory Temporarily”
on page 139. To use the LRU Sitting Time to tune memory, see Tuning
