I've been playing with 2.93.1 and 4.0.4 this weekend (the output screen
from 4.0.4 looks a bit nicer, but it doesn't do logging and gets
confused by 'all'). Once you've got a size of memory that it is able to
mlock, and assuming you are running in single user mode without swap,
I'd go with bad memory. Sorry.
Alternatively, if your cooling is marginal you might lock when the cpu
overheats. Or perhaps the power supply isn't up to the job. I forget
what you have, but both these problems are unlikely on sane hardware,
even my AmigaOne can get through hours of memtester without locking
(although hefty compiles with gcc-3.4 are a different story).
