Sorry, I should have included this information in my first post.
The hardware is a Dell 2550 poweredge with a 1GHz Intel 3, 500MB ECC
RAM, 2 SCSI disks in RAID and some intel NICS.
The OS is GNU/Linux 2.4.4 patched for Dell's RAID. The distro is
my own (based on LFS and Slackware). Library info below.
Here are some details from mysqlbug:

Fractional usage of swap indicates that the machine isn't being
pushed, and indeed the load is usually low.

I don't have a my.cnf, so I assume its all defaults - do you know
where I can find this out or would I be advised to work out my own
custom config for this machine based on the my-medium.cnf or
my-large.cnf files in share/mysql?

I currently have 500MB ECC RAM, supplied by Dell. I used to get this
problem on an old Linux box with some dodgy RAM. It would be fine
until I compiled big programs. This box has been fine though, I've
compiled the kernel no problem 10s of times.
Hopefully thats covered everything,
thanks again - Matt.
