David, Are you compiling on NFS mounted shares? We've seen problems like this that, I believe, were due to NFS issues related to the automounter. To be honest, I don't know if we really tracked down and solved the problem, but if this is along your alley, I can ask around and see...

We know that this is not the fault of the compiler but hope that someone in the community may have also experienced this situation and found a fix for it. We have searched the RedHat and www.kernel.org sites but found nothing that points to the situation we are experiencing. We have an 8 processor Dell server running RedHat 7.3 and are using g++ 3.2.2. What we see is g++ forks an as process which hangs in a non interruptible dormant state. The as process never seems to wake up and remains until the system is rebooted. Just yesterday we also experienced a hang with Ant/Java build where 7 Java sub processes were spawned and all appeared to be doing nothing. The parent Java process would occasionally wake up for a brief moment and then return to a sleep state. We believe this to be a kernel issue, but have not been able to find any references to an issue like this. There is also a twin system that seems to experience the issue less frequently, but that may just be to a variance in the system loading. Any pointers would be greatly appreciated. Thank you. -- Regards, David Highley Phone: (206) 669-0081 Highley Recommended, Inc.
