[ncr.communications] TOWER STREAMS 2k/4k Buffer Allocation Failures

vause@cs-col.ColumbiaSC.NCR.COM (Sam Vause) (05/23/91)

A couple of customer sites of late have reported a  problem  with
their  TOWER  32/700 systems running WIN-TCP/IP, where the 2k and
4k STREAMS buffers appear to be  in  consistently  short  supply.
The  strstat(1) utility usually displays failures associated with
these buffers.

(STREAMS  Buffers  are  allocated  on  a  priority  basis,   with
percentages  of  each  buffer  size allocated to low, medium, and
high priority STREAMS requests.  If there is  a  failure  at  any
point,  the failure is reported in strstat(1).  This explains why
one may see strstat(1) reporting failures, where the CONFIG value
is higher than the MAX value.)

The problem has been identified to  rooted  in  the  installation
process for the "17+ User Update" software product.  This product
incorrectly adjusts the STRLOFRAC parameter from 80 to 1000;  the
cure  is to change the value back to 80.   A kernel relink/reboot
is required to effect the change.

The problem was originally reported on SPEC# 116219. Notices will
be  included  in   the  product   Transmittal  Documents  at  the
Software  Distribution Centers to alert System Administrators  to
take corrective action.
