==========================

AlphaServer SC Version :  SCv2.5 UK1 
Kit Name: SCV25UK11106834 
Release Date: 22/Apr/2004
PTR: 153-2-1402
IPMT Number:  CFS.106834
Abstract: Out of memory in bucket 31, node hang

You will need to build and deploy kernels and reboot all domain nodes to
install this patch. This patch is not needed on the management station
(if any) and can not be installed there.


Description of Patch:
=====================
1. Fix for a problem in ics_elan that could leak memory in bucket 31 when
   that bucket was very busy. This would eventually lead to a node hang.
   The problem was most often seen on busy UBC mode SCFS file servers.

2. A change in how cluster alias traffic is sent over ics_elan especially
   with regard to confirmations that were causing "out of sequence" panics
   on ICS channel 7 (TUNL).

3. Makes extra oolmd memory available for GigE packets. This enhances
   performance on file servers that use GigE as their primary interface.

    # scrun -d all setld -l /nfs/SCV25UK1106834 SCV25UK1106834
    # scrun -d all BuildKernels
    # scrun -d all DeployKernels

    # sra shutdown -domains all
    # sra boot -domains all

    To remove the patch use the following commands:
    # scrun -d all setld -d SCV25UK1106834
