Re: Java GUI (JFC) locks the machine
I've noticed that the latest JDKs tend to crash the X font server (xfs) occasionally. Check to see if xfs is running, and if not, start it.

JDK1.3 on Linux with SMP
Hi all, We're running Red Hat Linux 6.1, kernel 2.2.12 and glibc 2.1.2 on Pentium SMP machines. After several hours of running, sometimes one node will crash, giving: Exception in thread "main" java.lang.OutOfMemoryError <> In fact, it's unlikely that there should be any memory problems and this error does not occur when running on a single node. It's also disturbing that each java process takes only about 40 percent of the processing capacity on each node, even though it could go up to 7 percent or more. So, Sun's JDK 1.3 doesn't seem to be working on SMP machines under linux. Any advice? Thanks. __ Do You Yahoo!? Yahoo!

Re: JDK1.3 on Linux with SMP
Very likely a monitor contention leak bug that has been fixed in hotspot, I think in beta refresh. btw the more details you can give a group like blackdown or Sun etc the better, java -version for example :*) I've been using SMP for a while, the only issue I've seen on linux is that the later versions of linux pthreads are more stable on SMP I would tell you a number but they are all called version 0.8 :*( regards calvin Java Linux wrote: > > Hi all, > > We're running Red Hat Linux 6.1, kernel 2.2.12 and > glibc 2.1.2 on Pentium SMP machines.

Sun's code base is littered with about two dozen occurrences of the *exact same message* for a variety of different resource outages. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Re: JDK1.3 on Linux with SMP
Uh, yeah, that's right. Sun's jdk says that it doesn't work on smp kernels. You'll have to use the latest blackdown version. The rc4 version didn't work on smp kernels because the jit it shipped with couldn't handle native threads, but supposedly the final release has fixed those bugs. Release candiate 4 did work on smp kernels using green threads or the tya jit.
