Buildworld on an Ultra1E - exception - what does it mean?

[Torfinn Ingolfsen]

Hello,

I'm running FreeBSD 5.3-BETA7 on an Ultra 1E (170). I have cvsup'ed
source using the tag RELENG_5_3) yesterday. I started a buildworld, and
it had been going for som time (some hours) before the machine suddenly
was dead. So today I restarted the machine, thgis time with a serial
console hooked up. I started the buildworld, and sure ebough, after some
hours it hung again. I don't know exactly how far it has gotten, but the
last thing it was compiling (before the hang) was 'fstream-inst.So'.

On the serial console, I got this message:

I don't know much about Sun hardware. Can anyone tell me what this
means, and what I can do about it?

Thanks.
