I was getting those too, more specifically signals 9, 10 and 11. These are often due to faulty memory or hardware. I used to get these signals when compiling big stuff on my older box, which turned out to have faulty RAM. You can also get them when your CPU is overclocked and unstable. I was getting these signals at random stages during my build of the JDK 1.4, and I tracked down the problem to Ultra DMA being enabled for my hard drive. It seems the old IDE controller on this old motherboard didn't like UDMA, as per syslog (which I found out much later, after trying all sorts of stuff). Reverting the hard drive to WDMA2 fixed the problem. By the way, have you tried compiling the kernel? This is often a good way to check your system's stability. If you get these signals there as well, it's extremely likely that the culprit is your hardware. Hope this helps you in some way.

Hi - I've got a problem installing the JDK on FreeBSD 4.8 (see "/usr/ports/java/jdk13 - make all dumps - any suggestions ?" on the FreeBSD Questions list for details) and as I don't know how to fix I was thinking that I might completely uninstall all Java related stuff and start again. So far I have obtained the Linux JDK, the sources for the JDK and the FreeBSD patchset for the JDK and done a 'make install'. In fact I've done a make install several times as the process fell over because certain dependencies weren't met and so I fixed those and restarted. I've now got to a point in the make where it just says 'illegal instruction'. So my question is what's the best way to clean every trace of Java from the box so I can start again and (maybe) get further this time ? thanks richard shea
