Subject Re: Build pauses on Linux
Date Tue, 25 Nov 2003 16:10:26 GMT
My build finally ran to completion. I used the 'export LD_ASSUME_KERNEL =
2.4.1' and I also did a reboot. I'm going to monitor it to see how it
behaves but it looks like all is good for now. What does 'export
LD_ASSUME_KERNEL = 2.4.1' do anyhow? Does it cause the JVM to thread
differently or something? Thanks for the tip!
