Say hello form me. Hi Ernst :) I've got an 1850, which I think is the same as a 2850, except in 1U form. I doubt it's a hardware problem. I'm guessing it's a problem somewhere in the linux32 code, but I don't know for sure. Since I wasn't able to determine the real problem, I can't give a surefire solution, but I do have some tips: 1. While you're building jdk15, switch to a UP kernel as it seems to help make the linux-sun-jdk14 a bit more stable. 2. Reinstall linux_base-8 and everything it depends on and everything that depends on it (don't know that this actually helps, but it can't hurt). 3. Make sure linprocfs is mounted. 4. Apply the patch in this message, or jdk15 will abort with SIGILL on your Xeons: http://docs.freebsd.org/cgi/mid.cgi?20050123040212.71599.qmail 5. During the build, make sure the box is as idle as possible. Make sure nothing more intensive than top is active (watching compile messages scroll by is OK). 6. Even if you have no problems with java during the build, it will die with an error about 2/3rds of the way through. Ernst provided me with some notes that got me around this error, so I'll reproduce them here: -----------------------------Snip------------------------------------- i had the same problem and solved it executing the last command which caused the error manually. Looks like the error comes because it's a very long command. Just put the command that comes between 'then' and 'fi' in a shell file and execute it manually in the directory work/j2sre/make/java/java (I'm not seating now in my amd64 FreeBSD computer but I think that was the directory). The compilation will go on without any problem if you resume it afterwards with a 'make build'. Try 'make build |& tee build.out' (if your shell is csh or tcsh) or 'make build 2>&1 | tee build.out' (if sh or bash). After the error comes, edit build.out and you will see the command causing it (takes about two pages). --------------------------------------------------------------------- After you restart the build, it might hang again with your java problem - it did for me once. All I can say is kill it, do a make clean, reapply the patch, and start the build again. On the bright side, once you do manage to get jdk15 built and installed, it should be quite stable. We haven't been able to get our to fail yet on UP or SMP with a -j12 buildworld going on in the background. Hope this helps. -Jon
