I report this in the hope that it might be useful. My machine crashed 
yesterday with the following messages. It was sort of alive, but not 
responding to network connections and when I tried to log in as root, Init 
said it was unable to fork(). At that point I hit the reset switch.  If you 
need other info please ask.

System: Cyrix i586/333 with 32MB RAM, ALi Mobo. OS: RH7.2/server with 
kernel.org 2.4.18pre1 kernel + Speedtouch USB patches. System disk is a 
single Fujitsu 30Gb IDE disk runing ext3.
