I have a very similar configuration here. A SS10/MP with 320MB RAM, hme
Fast-Ethernet and Fast-Wide SBus-Card (isp) (both unused) and a ST15150N
as single drive, with 512 MB swap space. I've started with a current
kernel 2.0C that caused a total freeze nearly once a day, the error each
time was "unable to allocate scsipi_xfer" and "unable to allocate ecb". I
then switched to 2.0D that seemed to solve this issue but showed another
one: after some time I got frequent "sbrk: grow ... failed, error 12". Now
I'm at 2.0E that hasn't produced this error yet, but instead I got
"virtual memory exhausted" during compilation, and no network daemons
would work anymore (no sshd, no smtpd, even if restarted). And I had the
same problems from 2.0C again. So I think the memory management code must
be broken in some way.
If the machine freezes it says "syncing disks..." on the console and
that's it. I have to go into the monitor with Stop-A and say reset, sync
won't work after a crash. The machine is only running as a mail server
based on postfix (currently 2.0.19) from pkgsrc.

This is what I have found in /var/log/messages:

This is the dmesg output of my configuration:
