Every time when i'am login to d3, there is a Error Message after the
normal login message.

"WARNING: Buffer attachment failed. Error 22"

Does anyone know what this message mean?

Are you running D3 Linux 7.4.2 on a RedHat 9 box? If so, your problem is

To quote Robert Burke in his reply therein:

What that means is that you are running the wrong version of D3. The
supported versions are:

D3/Linux 7.4.0 on Red Hat 9
D3/Linux 7.4.2 on Red Hat Enterprise

By running D3 7.4.2 on Red Hat 9, you are using the wrong memory map. The
error 22 is the least of your problems. If you need to stay on Red Hat 9,
you will need to install the supported 7.4.0 release.

i'm running D3 Linux 7.4.2 on RH Enterprise, but not with the original
RedHat-Kernel. i have built my own kernel, because the RH 2.4.21-ES
Kernel may have some IO-Scheduler problems (the thing is realy slow).
with a Vanilla 2.4.31 Kernel, the systems responses much faster.

I'm no expert on D3 internals (nor RedHat for that matter). But, it seems
likely (and this is only my "best guess" assumption here) that D3 doesn't
like something in your recompiled kernel.

Sorry, but I've have no idea what it doesn't like. For that, you'd need to
speak to Raining Data tech support. However, I'd expect their response to
be that you are running D3 on an unsupported RedHat version. (In the past
I've had similar responses from them when running patched versions of
RedHat, so unless they've changed their stance, expect the worse!) :-(

Having said that, they *should* be able to tell you what the error message
means and whether or not you're "safe" to continue using D3 without some
buffer or other having been attached.

At that stage you're in a position to decide whether you should run with the
buffer error and suffer the consequences, or whether you should run with the
vanilla kernel and suffer the consequences.

Apologies if I'm stating the obvious, but your previous post has been 24
hours without a reply so I thought I'd offer you the little I have.

Hope this helps in some way.

Hi Mike

Thank you for your help. I going back to the RH Standard Kernel, because
the read-performance on D3 seem's to be slower with the Vanilla
kernel.org Kernel.
