I used the full tar.gz from I use a "monolithic" kernel
with no modules. Here is a breakdown of the hardware/software on the
two machines:

Both have a Tyan 1562D dual CPU motherboard, 128MB parity memory (with
ECC mode turned on in the BIOS) and 3Com 3c590 ethernet cards. They are
all SCSI (no IDE).

Both are running sendmail 8.8.5 (news server is backup mail spooler),
gated R3_6Alpha_2 receiving OSPF routing updates (there are currently
about 60-70 routes), xntp 3.5f, and Apache. single Pentium 200, Adaptec 2940 (787x), DPT PM3224A (in
RAID0 mode). It is running INN 1.5.1sec2 with several bugfix and MMAP
patches. This system didn't last 2 days before it ran out of memory. dual Pentium 200, Adaptec 2940 (788x). It is a virtual web
server as well, with 23 aliases on eth0 (eth0:0 - eth0:22). This system
lasted about 2 days before it had to be rebooted because of no free RAM.
