Hi, I've compiled the newest 2.6.15.5 vanilla kernel on my FC4 box to replace the default stock kernel, but find a problem after my valinna kernel is put into use: the stack size shrinks from "10240KB" to "8192KB". Anyone know why? Is that because redhat have patched it? If so then anyone know the patch? The output is attached below. Thanks. Redhat stock kernel for FC4: [root@testnode01 ~]# uname -a; ulimit -a | grep stack Linux testnode01.example.com 2.6.15-1.1831_FC4smp #1 SMP Tue Feb 7 13:51:52 EST 2006 x86_64 x86_64 x86_64 GNU/Linux stack size (kbytes, -s) 10240 newly compiled vanilla 2.6.15.5 kernel: [root@testnode01 ~]# uname -a ; ulimit -HSa | grep stack Linux testnode01.example.com 2.6.15.5_64GB #4 SMP Mon Mar 6 14:39:14 PST 2006 x86_64 x86_64 x86_64 GNU/Linux stack size (kbytes, -s) 8192 Thanks. __________________________________________________ Do You Yahoo!?
