BTLAN failure

Hi dudes (sorry about the previous blank posting....finger problem...)

Got the following this AM, and assume a H/W problem, but find no match on ITRC:

**************************100 Mb/s LAN/9000 Networking**********************@#%
Mon Nov 24 SAST 2003 10:38:06.664995 ERROR Subsys:BTLAN Loc:00000
<7001> 10/100BASE-T driver could not map transmit buffer successfully
for adapter in slot(crd In#) 2.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Luckily the affected server is on an MC/SG cluster, and failover was done, but I need to fix this now.
Any bright ideas? Swopping the card WILL be done once I've eliminated any possible S/W or HWE patches.

Thanks, Robert-Jan.
Now that's one for the Forums Feedback: I did a search on "could not map transmit buffer" on ITRC, and got no hits......

I just got this same problem on ANOTHER server in the same cluster, so I reckon we're picking up garbage from the network.
I'm going to reset the lan card using lanadmin, and see what happens.

I didn't check that link, but also make sure you have the latest unified btlan patch...

PHNE_28799
s700_800 11.11 100BT unified driver cumulative patch

That addresses mapping issues.

In MC/SG cluster, There may be issues if you have your ARP time out setting in routers as a default value. This made our lan card hang like this. Please ask your Network Admin to reduce that time. Hope this helps.

The patch will be checked, and I'll talk to the router guys about the ARP timeout.
Thanks all.
