Lately, I've been having lots of trouble with my NetBSD box just locking 
up on me... usually the hard drive light stays on when it locks up, so I 
have a feeling it's maybe in the scsi code or something. 

The box is a IIci, with 16 megs of ram. I was using the internal 250 meg drive 
as my root volume, and then I added a second external drive, which didn't
work well with NetBSD. When the I/O got to be too much for that drive 
(a 2-year old Micropolis 1-Gig from APS), that drive would just click and then
spin down. So I put on a 730 Meg Quantum from APS. It has been working the best
out of anything I've tried yet (with an external drive anyway).

The only problem is that it still locks up once a day... usually when there is
alot of I/O going on. Yesterday it locked while I was compiling Perl. Today,
it locked when a daily output cron job was going at the same time I started
up Elm. 

I'm currently using the NetBSD 1.1 release of everything. I've tried newer
kernels, and they don't help. In fact, the NFS_17 kernel from eskimo.com 
locked at the "Changing root device to sd1a."

I'm not using the internal disk at all at the moment... it locked up every 5 
minutes when I had that in use along with the external. I finally had to 
reformat everything and reinstall from scratch because the file system was
just too messed up.

Does anyone have any ideas of what might be causing this? I currently run 
all the normal daemons, plus sendmail, and httpd. One possibility I came up
with was that maybe the drive is getting too hot and with all that I/O going
on, it has to recalibrate itself. My office is usually around 80-90 degrees 
(it sucks... yes.) 

Thanks,
Kelly
