Folks, I have been trying to build and use kernels with NUMA enabled ( in this case : 2.4.21-171) Several user-level commands now segv and core dump, in particular 'ps' and 'vmstat'. Using strace, I can see that they are calling 'read' on /proc/meminfo. open("/proc/meminfo", O_RDONLY) = 5 lseek(5, 0, SEEK_SET) = 0 read(5, " total: used: free:"..., 1023) = 1023 but /proc/meminfo is much bigger with NUMA enabled: # wc /proc/meminfo 42 167 1243 /proc/meminfo Has anyone else met this ? - and if so what else apart from 'ps' and 'vmstat' would need to be recompiled? -- Yours, Daniel. -------------------------------------------------------------- Dr. Dan Kidger, Quadrics Ltd. daniel.kidger@quadrics.com One Bridewell St., Bristol, BS1 2AA, UK 0117 915 5505 ----------------------- www.quadrics.com --------------------
