Software Increment Release Notes
================================

Increment ID:   I05A1730
Date created:   May 4, 2000
CSR number:     50318022

Title: Memory Robustness Patchback

Detailed Description of Increment:  
----------------------------------
This patch includes two enhancments and one fix. The first
enhancment is the Memory leak robustness which will swact 
the APU when free memory has run out. The second enhancement
is the addition of the STOR log. This log will be produced
at the end of the REX test every night so that potential 
memory issues can be tracked. The fix addresses a store 
gobbler in the NLIC maintenance software. The original code
for these issues is included in the AN18 software release.

     If you select option 2, a list of NEs in the span of control appears.

Test Instructions:
------------------
1. Apply this increment
2. Monitor for anything out of the ordinary (SWERRs, TRAPs, etc.)
Please be aware of the following circumstances when working with
this patch:

When this patch is applied then removed and applied again
this patch will SWERR several times. These SWERRs are
produced because the STOR log is defined on the initial
application. When it is applied any subsequent time after
that the system SWERRs to alert the user that the log 
already exists. This DOES NOT have any effect on the 
functionality of the patch. 

3. Ensure system remains stable
