I have a 256MB UP PII 933 MHz. When running the included program with an option of 200 (serving 200 clients with streaming data ? 10MB... on first run it creates the data, from /dev/urandom - overkill from /dev/null is ok!) ddteset.sh 200 [testcase initially written by Roy Sigurd Karlsbakk, he does not get into this - but he has more RAM] the 2.4.18pre7 goes into deep swap after awhile . It is impossible to start a new login, et.c. finally the dd processes begins to be OOM killed... not nice... the 2.4.17-rmap12b handles this MUCH nicer! /RogerL -- Roger Larsson Skellefte?
