Mark,

The first thing I'd do is increase the maximum alloc short term memory = 4200000
statment to at least 5 meg.  I've been able to kill my server while syncing the
name service domain by having a low value set.  As to how large an increase to
apply; use the resource in use screen of monitor to gauge what you use now and
watch it during one of your "monster" copies.

Good luck,

Hello, everyone.

We now have about 50 NetWare servers on our campus internet, 8 of these
I'm personally responsible for.  All 8 of my servers now run NW3.11.
There's been this nagging problem happening for a very long time (ever
since my first NW3.0 installation).  Fortunately, though the problem
is fatal when triggered, the circumstances that cause the problem are
not normally encountered.

When I attempt to perform large-scale writes to a NetWare volume, the
disk that volume resides on will deactivate.  Since we frequently have
one large disk partitioned into three volumes, this deactivation
causes the server to go into an endless-loop of "Volume xxxx write
preread fail..." errors.  However, the problem also occurs when
separate physical disks are used for each volume.

So, I can pretty much kill any of my NW3.x servers at will.  All I
need to do is:

    Try to copy all files from sys:public to apps:public,

  or

    Attempt to back-up one server to another via NBACKUP,

  or

    Attempt to back-up a client to the server with Central Point
    Backup (or another similar program).

Following is a typical AUTOEXEC.NCF for our servers.  The platform
is an HP Vectra RS20 (20MHz 386) with an SMC Ethercard Elite 16 nic,
Adaptec AHA1542 SCSI controller, and a Micropolis 2.0GB drive.  The
server has 16MB RAM, and is protected by an APC 600VA UPS.

Any suggestions would be greatly appreciated.  Note that I don't
believe this is hardware related, since all 8 servers have different
hardware configurations but experience the same trouble from time-to
-time.

Thanks in advance.
